Abstract:
<p>As a part of ongoing research projects at University West in the area of robot welding applications, a study was looked-for in the field of feedback control of robot systems with external sensors. A literature survey was performed in this field. A virtual instrument was developed in a PC using the LabView software from National Instruments. The instrument receives a signal from a force sensor, converts the input data and sends out the computed signal on a configured serial port. This information is then received by the robot system to be used to control the robot trajectory. The system was

Abstract:
The concept of merging exercise equipment with video games, known as exergaming, has the potential to be one of the main tools used in addressing the current rising obesity epidemic. Existing research shows that exergaming can help improve fitness and additionally motivate people to become more active. The two key elements of attractiveness - how much people want to play or use the exergaming system; and effectiveness – how effective the exergaming system is in actually increasing or maintaining physical fitness, need to be maximised to obtain the best outcomes from an exergaming system; we pu

Abstract:
Hierarchical scheduling provides predictable timing and temporal isolation; two properties desirable in real-time embedded systems. In hierarchically scheduled systems, subsystems should receive a sufficient amount of CPU resources in order to be able to guarantee timing constraints of its internal parts (tasks). In static systems, an exact amount of CPU resource can be allocated to a subsystem. However, in dynamic systems, where execution times of tasks vary considerably during run-time, it is desirable to give a dynamic portion of the CPU given the current load situation.

Abstract:
Scanning-electron-beam lithography (SEBL) is the primary technology to generate arbitrary features at the nano-scale. However, pattern placement accuracy still remains poor compared to its resolution due to the open-loop nature of SEBL systems. Vibration, stray electromagnetic fields, deflection distortion and hysteresis, substrate charging, and other factors prevent the electron-beam from reaching its target position and one has no way to determine the actual beam position during patterning with conventional systems.

Abstract:
This thesis presents decentralized model reference adaptive control techniques for systems with full-state feedback and systems with output feedback. The controllers are strictly decentralized, that is, each local controller uses feedback from only local subsystems and no information is shared between local controllers. The full-state feedback decentralized controller is effective for multi-input systems, where the dynamics matrix and control-input matrix are unknown. The decentralized controller achieves asymptotic stabilization and command following in the presence of sinusoidal disturbances

<p>In this thesis we apply linear feedback control to spatially evolving flows in order to minimize disturbance growth.

This reconstructed flow state is used to determine the control feedback which is applied to the Navier--Stokes equations through properly designed actuators. Since the control and estimation gains are obtained through an optimization process, and the Navier-

Stochastic thermodynamics provides a clear definition of entropy production and the framework of fluctuation theorems has allowed many general results to be obtained for nonequilibrium systems. Notably, relationships for work and free energy in nonequilibrium systems as well as second law-like inequalities have been obtained. A recent extension to this framework has been the addition of feedback and the generalisation of the previously obtained inequalities to incorporate information quantities related to control and feedback.

We use the macroscopic modeling approach, where pedestrians are treated in an aggregate way and detailed interactions are overlooked. The models representing evacuation dynamics are based on the laws of conservation of mass and momentum and are described by nonlinear hyperbolic partial differential equations. As such the system is distributed in nature. We address the design of feedback control for these models in a distribute
