Energy is a strategic focus area for research and education at University of Ontario Institute of Technology (UOIT). In the area of energy engineering and science, innovative programs are offered in energy systems engineering, nuclear engineering, energy engineering (an option in mechanical engineering), and energy and the environment (an option in physics). The academic highlights of the programs...
The fully automated design of optimal or near-optimal feedback controllers is considered for least-pth and minimax cost functions. Solutions are obtained by approximating to the desired optimal output by a rational function. Optimal results for a 2nd-order model and suboptimal responses for the corresponding 7th-order linear system are used to illustrate the method.
A minimax objective is proposed, based on measuring the deviation of an actual response from the one to be approximated, in a direction that is everywhere perpendicular to the specified response. A weighting sequence is derived, which, in conjunction with the conventional sample error, gives the desired objective function.
