<p>The aim of this thesis is to develop the knowledge about nonlinear and/or adaptive solid fuel boiler control at Vattenfall Utveckling AB. The aim is also to make a study of implemented and published control strategies.</p><p>A solid fuel boiler is a large-scale heat (and power) generating plant. The Idbäcken boiler studied in this work, is a one hundred MW furnace mainly fired with wood chips. The control system consists of several linear PID controllers working together, and the furnace is a nonlinear system. That, and the fact that the fuel-flow is not monitored, are the main reasons for

Abstract:

An event-driven, sequential, process control system was designed for International Isotopes, Inc., to automate and remotely control a target station at the company's linear accelerator facility. The designed system consisted of two major sections: a software program (virtual instrument), which was developed by LabVIEW, and a hardware interface (FieldPoint Modular Distributed I/O System by National Instrument), which had to be a pre-developed system that did not require customization. The designed virtual instrument was tested on a simulation model that mimed the target station. The result was

Abstract:

This work presents the application of the Linear Quadratic Tracker (LQT) for the automatic landing system of passenger transport airplanes. The design method to achieve an autoland flare law with improved performance and disturbance rejection is described. With this method the design is direct and more formal thus avoiding the somewhat time consuming and more ad-hoc design iterations currently practice in industry. Although the design technique has been used for a autoland system, the approach is general enough to be used in other control applications. The structure of a traditional flare cont

Abstract:

In this work, we present a novel robust dual adaptive model predictive control scheme for linear discrete-time systems with parametric uncertainty in the output and affected by a state-disturbance and a measurement noise. The proposed MPC framework promotes learning of the unknown parameters and in the meantime tracks a desired target output despite the presence of a state disturbance. This is possible through a suitable restriction of the state, input and output constraints that covers the whole possible range of the state disturbance. We prove that the proposed controller is practically stab

<p>There are occasions when it is preferable that an aircraft flies asclose to the ground as possible. It is difficult for a pilot to predict the topography when he cannot see beyond the next hill, and this makes it hard for him to find the optimal flight trajectory. With the help of a terrain database in the aircraft, the forthcoming topography can be found in advance and a flight trajectory can be calculated in real-time. The main goal is to find an optimal control sequence to be used by the autopilot. The optimization algorithm, which is created for finding the optimal control sequence, has

Abstract:

When designing controllers with robust performance and stabilization requirements, H-infinity synthesis is a common tool to use. These controllers are often obtained by solving mathematical optimization problems. The controllers that result from these algorithms are typically of very high order, which complicates implementation. Low order controllers are usually desired, since they are considered more reliable than high order controllers. However, if a constraint on the maximum order of the controller is set that is lower than the order of the so-called augmented system, the optimization probl

Careful treatment of the initial state of the model is quite important, in particular for short batch sizes.

Abstract:

When controlling safety-critical systems with uncertain components, constraint satisfaction is not only vital but also a major challenge. Model predictive control (MPC) is a common solution to satisfy strict state and input constraints. However, on its own it is not able to deal with uncertainties. Hence, it is necessary to robustify this controller. With this aim, recently contributions have been provided on a tube-based robust MPC scheme for state and input constrained linear systems subject to dynamic uncertainties described by ρ-hard integral quadratic constraints (IQCs). Nonetheless, ofte

Abstract:

Les principales contributions de cette thèse concernent le développement de méthodes pour la synthèse de contrôleurs et pour l'analyse de la stabilité des systèmes linéaires, soit variant ou invariant dans le temps. Concernant les systèmes invariant dans le temps, le but est la synthèse de contrôleurs robustes d'ordre réduit pour les systèmes en temps continu qui présentent des paramètres incertains. La méthode présentée pour la synthèse est basée sur une technique en deux étapes, o'u un gain de retour d'état est construit dans la première étape, et appliqué à la deuxième, fournissant le contr

Abstract:

The thesis describes the design of a novel non-linear controller for the plasma vertical position in a Tokamak that maximizes the stability region and is robust to certain disturbances and measurement noise. The plasma vertical position in a Tokamak can be open loop unstable with time-varying dynamics. The limitation in the output power of the control amplifier makes the time varying unstable system particularly difficult to control. Fixed-coefficient linear controllers usually fail to maintain control in the presence of large disturbances, like Edge Localized Modes (ELMs), which saturate the

Abstract:

The thesis investigates control system integration in ADAMS and the thesis presents appropriate knowledge related to the topic as multi body system, acting forces between road and wheels, equation of motion regarding to the haulers, traction control system and differential locks. The emphasis of the thesis is to implement and test the automatic traction control (ATC) for the hauler into ADAMS and Simulink models. The ATC models are based on certain requirements provided by Volvo Construction Equipment. As expected, results indicate that the ATC model operates during simulation for various road
