Abstract:
A supervisory process control approach to machining is presented in this paper, and demonstrated by application to a drilling operation. The supervisory process control concept incorporates optimization and control functions in a hierarchical structure. This approach utilizes feedback measurements to parameterize the constraints of a process optimization problem whose solution determines both strategies and references for process control. For this particular drilling operation, a three-phase strategy (utilizing a combination of feed, speed, and torque control) evolved due to inherent variation in constraint activity as a function of hole depth. A controller comparison study was conducted which demonstrates the advantages of this approach compared to (1) uncontrolled “conventional” drilling, (2) feed and speed controlled drilling, and (3) torque and speed controlled drilling. Benefits of reduced machining time, improved hole quality, and the elimination of tool breakage are demonstrated, and the potential economic impact is highlighted for an example production application.

Abstract:
This work presents a methodological framework for the design of a resource-aware supervisory control system for process networks with model uncertainty and communication resource constraints. The developed framework aims to balance the objective of closed-loop stabilization of the overall network with that of meeting the local performance requirements of the component subsystems while keeping the rate of data transfer between the local control systems to a minimum. First, a quasi-decentralized networked control structure, with a set of local model-based controllers communicating with one another over a shared communication medium at discrete times, is designed. A Lyapunov stability analysis of the closed-loop system is then carried out, and the results are used to derive appropriate bounds on the local model state estimation errors as well as the dissipation rates of the local control Lyapunov functions. These bounds are used as stability and performance thresholds to trigger communication between the local control systems and a higher-level supervisor that coordinates the transfer of state measurements between the distributed control systems. A breach of the local stability and performance thresholds generates alarm signals which are transmitted to the supervisor to determine which subsystems should communicate with one another. The supervisor employs a composite Lyapunov function to assess the impact of the local threshold breaches on the stability of the overall closed-loop system. The supervisory communication logic takes account of the evolution of the local and composite Lyapunov functions in order to balance the stability and local performance requirements. Finally, the developed framework is demonstrated using a representative chemical process network and compared with other unsupervised event-based control approaches. It is shown that the supervisory event-based control approach leads to a more judicious utilization of network resources that helps improve closed-loop process performance in the presence of unexpected disturbances and input rate constraints.

Abstract:
The implementation of the administrative reform of the control and supervisory sphere in the Russian Federation has caused serious transformations in the activities of authorities implementing the functions of state control (supervision). The adoption of Federal Law No. 248-FZ dated 07/31/2020 "On State Control (Supervision) and Municipal Control in the Russian Federation" strongly influenced both external and internal aspects of administrative procedures implemented by executive authorities in the course of their exercise of state control (supervision) functions, which requires serious scientific analysis. One of the main applied scientific methods of cognition and description of legal reality is the classification of the studied objects. Within the framework of this article, the author studies the system of administrative control and supervisory procedures, identifies their various types and classifies them.To conduct the research, the classification method was used primarily as one of the main methods of scientific knowledge of law, as well as legal methods proper, including the formal legal method. As a result of the study, the main major characteristics of administrative control and supervisory procedures were analyzed (reconfiguration of types of state control and supervision, scaling of the control and supervisory sphere, establishment of new forms of control (supervisory) measures), the main scientific views on the classification of administrative control and supervisory procedures were considered. As a result, the grounds for classifying the procedures under consideration were formulated, including the form of the control (supervisory) event, the supervisory authority involved in the procedure and the area of state control (supervision). There are several types of administrative control and supervisory procedures, including standard and special procedures, monosubject and polysubject procedures, as well as a variety of procedures depending on the sphere of public relations, in which mandatory requirements are established, the verification of compliance with which is carried out within the framework of state control (control procedures in the field of communications, transport, etc.).

Abstract:
This thesis presents two approaches to the hierarchical supervisory control of discrete event systems (DES) modelled as finite deterministic automata.<br>First, a hierarchical control theory based on the aggregation of states is presented that differs from the standard approach to hierarchical supervision which mainly employs formal language methods. A high-level (i.e. aggregated) deterministic automaton model is defined that uses notions of dynamical consistency (DC) in the definition of high-level transitions. A Trace-DC condition is then defined on any given state-space partition which ensures that (i) trajectories in the low-level system are always represented in the high-level system, and (ii) trajectories in the high-level model are realized by trajectories in the low-level system. It is also shown that the Trace-DC condition ensures low-level controllable behaviours (languages) are represented as high-level controllable behaviours.<br>The (Non-Blocking) In-Block-Controllability condition on partitions is then defined that ensures that behaviours that are expressly controllable in the high-level model can be achieved through the control of high-level transitions between blocks combined with local state - feedback controls in each block. A so-called vocalised lifting algorithm is proposed for the construction of Trace-DC partitions. It is shown that this formulation of hierarchical supervision satisfies conditions of hierarchical consistency from the literature on formal language-based hierarchical supervisory control theory.<br>The approach is illustrated with several examples of manufacturing production lines, including a re-entrant transfer line and a line with two sequential queues. An application to the embedded control of home appliances (washing machines) which motivates the approach is summarised.<br>Second, a notion of systems of interacting finite deterministic automata is formulated via a newly proposed multi-agent ( MA) product. The transition relation of the MA product is shown to be the intersection of the transition relations of two associated products, the vector state-dependent synchronous product and the simultaneous product. It is shown also that the language accepted by the MA product is the intersection of the so-called embedded constraint language of each agent.<br>The supervision of one agent by another is then considered and it is shown that the standard finite automata realization for a supervisor can be employed as the model for the supervising agent.<br>A line of research is then initiated on the centralised, decentralised and hierarchical supervision of MA product systems. It is shown that the MA product of behaviours that are individually and independently controllable with respect to each agent forms a controllable behaviour in the MA product system.

Abstract:
Mit der Automatisierung geht stets erneut die Frage nach der Funktionsallokation einher. Diese lässt sich vereinfacht wie folgt formulieren: Welche Aufgaben bzw. Funktionen soll die Automation und welche der Mensch ausführen? Abwendend von traditionellen Ansätzen maximaler Automatisierung und statischer Aufgabenteilungen haben sich heute dynamische Ansätze der Funktionsallokation bzw. kooperativen Automation durchgesetzt, bei denen sich Operateur und Automation die Kontrolle für bestimmte Aufgaben während des Prozesses teilen oder übergeben können. Die Ausgestaltung dieser kooperativen Automation wirft insbesondere zwei Fragen auf: Wer hat (wann wieviel) Kontrolle? Und wer entscheidet darüber? Diese Fragen nach Kontrolle und Autorität bilden die Grundlage für das theoretische und empirische Anliegen dieser Arbeit. Auf Basis einer umfangreichen literaturbasierten Diskussion der Fragen wird ein eigenes Rahmenmodell vorgeschlagen. Dieses erlaubt, anhand der Aspekte Authorität und Kontrolle, konkrete und trennscharfe Kooperationsformen zwischen Operateur und Automation zu beschreiben. Der einfachste Fall einer Zusammenarbeit zwischen Operateur und Automation wird sodann in einer Studie mit 81 Operateuren untersucht. Es interessiert, ob sich die Leistung von Operateuren, welche bei der Prozessüberwachung und -führung optional mit einer automatischen Unterstützung zusammen arbeiten können, im Vergleich zu Operateuren ohne eine solche automatische Unterstützung verbessert. Für bestimmte Leistungsindikatoren können in der Tat höchst positive Effekte der automatischen Unterstützung ermittelt und konkrete Interaktionsmuster der Operateure in der Kooperation mit der automatischen Unterstützung beschrieben werden. Die theoretischen und empirischen Ergebnisse der diesere Arbeit liefern eine Grundlage für differenzierte Bewertungen und somit auch Empfehlungen spezifischer Kooperationsformen, die gerade im Hinblick auf die Ausgestaltung kooperativer Automation noch rar sind.<br>Automation has always been accompanied by the question of function allocation, that is: which tasks and/or functions should be executed by the machine vs. by the human? Today, dynamic function allocation or cooperative automation has become the dominant approach, which allows for a more flexible sharing and trading of control between operator and automation. However, how cooperative automation is put into practice remains mainly an open question. Two central aspects have to be dealt with: Who should execute a certain function, i.e. have control (and when)? And who should decide about it? These questions of control and authority are central to this thesis. Based on an extensive literature review, a theoretical model is proposed. This model allows for a classification of specific forms of control between operator and automation based on authoriy and control. In an empirical study the effect of the most simple form of cooperation is investigated regarding its effect on performance of 81 operators. It is assumed that supervisory control performance of operators benefits from this form of cooperation with automation. Thereby supervisory control performance of operators cooperating with automation is compared to performance of operators who were not provided with such automation, i.e. had to supervise and control fully manually. Results show, that cooperation with automation has a positive effect on certain performance indicators. Also interaction patterns of operators cooperating with automation are investigated in detail. Both, the theoretical and empirical approach in this thesis provide a profound basis which allows for a more sophisticated evaluation and recommendation of forms of cooperation between operator and automation. So far, such recommendations are rare in Human Factors Research but they are desperately needed, especially when it comes to the implementation of forms of cooperative automation.

Abstract:
A method is presented to solve supervisory control problems of discrete event systems and produce divergence-free controllers, which guarantee to avoid unbounded internal communications. The method is described in terms of process spaces, a formalism to model concurrent systems, and applied to safety models. Semantics mappings are described, which relate process spaces to I/O automata and other labeled transition systems. Divergence-free solutions are obtained based on a strong notion of divergence freedom. Our method, which produces the solution for a supervisory control problem, can also detect the absence of such solution and helps to obtain synthesizable specifications for the solutions as well. Finally, a case study is considered where the supervisory control formulation is used to derive the specification of a divergence-free protocol converter to interface two mismatched communication protocols.

Abstract:
In the present climate of energy conservation and CO2 emission consciousness, building heating, ventilating and air conditioning (HVAC) systems are required to achieve thermal comfort and indoor air quality in the most energy efficient manner possible. To this end optimising the use of natural ventilation is considered an area which can significantly reduce both the occupants discomfort and the energy consumption. The ability to effectively control the indoor environment would considerably enhance the use of natural ventilation. The overall aim of this research is to develop, commission and evaluate a fuzzy rule-based controller which can vary the resistance of ventilation opening in order to maintain an acceptable comfort conditions in the occupied space. The design of the fuzzy control system starts by establishing certain quantization levels for the input/output variables along with corresponding membership functions. Aspects of input and output variable choice together with their linguistic labels are explained and presented. Control rules are defined based on the off-line thermal modelling, experimental results and through discussions with experts. A dynamic air flow distribution is investigated through a series of experiments for different environmental conditions and opening levels without any control action. Three rule-bases of different complexity are developed and presented. All solutions are simulated in an input-output space and their differences presented in more detail through examples of the Mamdani inference method application. Controller validation is initially carried out using simulation as this offers the possibility of testing controllers under extreme conditions regardless of test room physical limitations. Simulations are carefully designed to allow simultaneous comparison of different controllers' performances. Then on-line validation is carried out in the test room by measuring the air flow distribution with and without the controller in action. A naturally ventilated test room and its instrumentation is set up. A controller commissioning methodology is established, involving the choice of software and hardware platforms and data acquisition methodology.

Abstract:
Robots and other automated systems have potential use in many different fields. As the scope of robot applications that robots are used for increases, there is a growing desire to have human operators manage multiple robots. Typical methods of enabling operators to multi-task in this way involve some combination of user interfaces that support human cognition and advanced robot autonomy. Our research explores a complementary method of managing multiple robots by utilizing operator teams. The evidence suggests that for appropriate task scenarios, two cooperating operators can be more than twice as effective as one operator working alone.

Abstract:
Human intervention in automated manufacturing systems may result in faults in material flow leading to incoherent behavior of the control system. Particularly when multiple workpieces can be operated concurrently, the design of a programmable logic controller (PLC) that can handle such nondeterministic events is a complex task that justifies the use of formal methods such as the Supervisory Control Theory (SCT). The main objective of this work is the use of SCT for the systematic design of the automation system of an electro-pneumatic station of a Modular Production System prone to faults in the material flow. A code generation tool has been used to translate the modular supervisors into an IEC61131 PLC program, whose automata-based structure has been exploited by several functionalities of a SCADA System. The implementation of supervisory control allows the station to flexibly process five workpieces simultaneously, with conformance to functional requirements and with safety to deal with the nondeterministic removal of workpieces along the station.

Abstract:
Abstract Supervisory control (SC) theory, coupled with the TCT modeling package (Wonham, 1994), is theoretically powerful and practically useful. However, due to the lack of an efficient method to transform the SC model into operational control logic, this theory has found limited applications in manufacturing. This paper presents a method to rapidly prototype operational control software for an automated manufacturing system using SC theory. Given the control specification of a manufacturing workcell, an SC model can be developed using the TCT package. By transforming the SC model into an MPSG-based model (Smith, 1992), the modified MPSG builder can generate the corresponded control logic in the form of C++ source codes. After the equipment-level control and information handler functions are inserted into the control logic, an executable computer-based controller on the shop floor can be immediately compiled.

Abstract:
Future vertical lift (FVL) missions will be characterized by increased agility, degraded visual environments (DVE) and optionally piloted vehicles (OPVs). Increased agility will induce more frequent variations of linear and angular accelerations, while DVE will reduce the structure and quality of the out-the-window (OTW) scene. As rotorcrafts become faster and more agile, pilots are expected to navigate at low altitudes while traveling at high speeds. In nap of the earth (NOE) flights, the perception of self-position and orientation provided by visual, vestibular, and proprioceptive cues can vary from moment to moment due to visibility conditions and body alignment as a response to gravitoinertial forces and internally/externally induced perturbations. As a result, erroneous perceptions of the self and the environment can arise, leading ultimately to spatial disorientation (SD). In OPVs conditions, the use of different autopilot modes implies a modification of pilot role from active pilot to systems supervisor. This shift in paradigm, where pilotage is not the primary task, and where feedback from the controls is not available, has consequences. Indeed, space perception and its geometric properties can be strongly modulated by the active or passive nature of the displacement in space. In view of the link between the level of automation and Sense of Agency (SoA), it is of particular interest to examine whether agency mechanisms can modulate the level of visuo-vestibular integration in tasks of action perception and control. An experiment was conducted using the NASA Ames vertical motion simulator (VMS) to evaluate the effects of optical and gravitoinertial cues in the assessment of altitude in contour terrain flight. Seven U.S. Army pilots participated in the experiment. The aim of the proposed research was a) to establish the relative contribution of visual and gravitoinertial cues as a function of the quality of the visual cues (good vs. degraded), and the presence or absence of gravitoinertial cues, b) to determine the role of manual control vs. supervisory monitoring control on the estimation of altitude, and c) study the interactions between the nature and the quality of the sensory cues and the type of control. For the supervisory control condition, the results showed that the gravitoinertial component played a significant role in the estimation of ground height, but only in the case where the optical structure did not efficiently specify the actor-environment interaction. The improvement of the tracking performance in the visuo-vestibular setting as compared to a visual only setting when the visual cues were poor indicates some level of multisensory integration. Preliminary results for the manual control condition suggest the gravitoinertial cues contribute to an increased safety margin in presence of obstacles, particularly in DVE. Altitude accuracy and precision will then be compared for the manual and supervisory control tasks and discussed in the context of the Sense of Agency theory.

Abstract:
Small modular reactors (SMRs) can provide the United States with a safe, sustainable, and carbon-neutral energy source. Because of their small size and, in many cases, simplified nuclear island configurations, it is expected that capital costs will be less for SMRs compared to that of large, Generation III+ light-water reactors. Advanced SMRs (AdvSMRs), which use coolants other than water as the primary heat transport medium, introduce several passive safety concepts and controls features that further reduce the complexity of primary system designs by eliminating redundant components and systems. Under U.S. Department of Energy (DOE) Office of Nuclear Energy (NE), the Supervisory Control of Multi-Modular SMR Plants project was established to enable innovative control strategies and methods to supervise multi-unit plants, accommodate shared systems, identify opportunities to increase the level of automation, define economic metrics based on the relationship between control and staffing levels, and permit flexible co-generation operational regimes. This paper documents current findings from the Supervisory Control project. Specifically, it defines and documents strategies, functional elements, and an architectural structure for supervisory control of a representative generic AdvSMR plant. More specifically, this research advances the state-of-the art by incorporating decision making into the supervisory control system architectural layers through the introduction of tiered taxonomy of plant systems and subsystems. The proposed architecture has the features of planning and scheduling, analyzing plant status, diagnosing problems as they develop and predicting potential future problems, making decisions based on these features, and generating validated commands to lower control layers in the architecture.

Abstract:
The class of buildings designated as commercial is comprised of many different architectures and functions, which presents a challenge when developing demand management strategies that are applicable across this field. Most advanced controllers are based on a model of the thermal loads in the building envelope. These models do not directly extrapolate to measures of power consumption, which is what building owners are ultimately interested in managing. In this work, we develop models of power use that can be easily tailored to model power demand in any commercial building with advanced sensing and metering. We address how existing models of the building temperature states can be incorporated into our framework. Specifically, we show how Auto-Regressive models with eXogeneous (ARX) inputs can be used for superior day-ahead forecasting of demand, and how to formulate the models in a way that is meaningful at the supervisory level. These models provide more flexibility in the design of a supervisory controller for building energy management and the information they provide is crucial for bridging the gap between buildings and utilities in the smart grid.
