Systems Control

Graduate Course Descriptions

ECE 557F Systems Control (Core Course)
M. Maggiore
Fundamentals of linear time-invariant control systems.  State space modeling and control design, controllability, stabilization, pole placement controllers, observability, Kalman filters, observer design, optimal control, tracking controllers.  Labs:  real-time control experiments on design techniques.   Course credit is not available for students who have taken ECE 410.  Prerequisite: ECE 356. Note:  Students can take only one of ECE1619 or ECE557.

ECE 1617H Large Scale System Theory and Control I
E.J. Davison
This course is an introduction to the control of large scale systems: decentralized fixed mode characterization/computation, interconnected systems, decentralized control, decentralized pole assignment, decentralized robust servomechanism problem, expanding system control problem.  Prerequisites:  ECE 410/411 or 557.

ECE1619H  Linear Geometric Control Theory
M.E. Broucke
The course presents a more advanced treatment of linear control theory via the geometric approach. The coverage roughly corresponds to the first six chapters of "Linear Multivariable Control: A Geometric Approach", by W.M. Wonham. We adopt the abstract algebra approach of the text to study controllability, observability, controlled invariant subspaces, controllability subspaces, and controllability indices. These concepts are applied to solve the problems of stabilization, output stabilization, disturbance decoupling, and the restricted regulator problem. Areas of current research in linear geometric control will also be discussed.

Course description to be announced prior to scheduling of course.


ECE 1636H Control of Discrete Event Systems I
W.M. Wonham
This course is an introduction to the control of discrete, asynchronous, nondeterministic systems like manufacturing systems, traffic systems, and certain communication systems. Architectural issues (modular, decentralized and hierarchical control) are emphasized. The theory is developed in an elementary framework of automata and formal languages, and is supported by a software package for creating applications. There are no special prerequisites.

ECE 1637H Control of Discrete Event Systems II
W.M. Wonham
This course is a continuation of ECE 1636H, and is conducted on a seminar basis. Participants will present and discuss articles in the current literature, and complete a project that could lead into graduate research in the discrete-event system area. Topics recently examined include controlled Petri nets, min-max algebra, real-time control via timed-transition-models (TTMs), recursive process algebras, and state charts. Prerequisite:  ECE1636.

ECE 1639H Analysis and Control of Stochastic Systems I
R.H. Kwong
This is the first course of a two-term sequence on stochastic systems designed to cover some of the basic results on estimation, identification, stochastic control and adaptive control.  Topics include:  stochastic processes and their descriptions, analysis of linear systems with random inputs; prediction and filtering theory:  prediction for ARMAX systems, the Kalman filter and the Riccati equation; stochastic control methods based on dynamic programming; the LQG problem and the separation theorem; minimum variance control.

ECE 1640H Analysis and Control of Stochastic Systems II
