Lumped System Theory

ECE60200

Credit Hours: 3

Learning Objective:
1. Promote in-depth understanding of basic calculations, applications, & theoretical concepts of state variable approach to system theory from basic vocabulary & examples to general solution of linear & time varying state model, to critical material on controllability, observability, & stability.
2. In order to achieve "1", the student must
(i) understand the basic vocabulary of system theory & state variable model formulation
(ii) apply basic principles & techniques to simple and complex modeling & analysis problems
(iii) theoretically analyze complex state variable problems, re: (a) computing solutions, (b) controllability, (c) observability, and (d) stability
(iv) critically evaluate procedure used to obtain accurate solutions.
3. Foster developmental thinking & pressured creativity in problem solving, i.e. by giving someone a fish, one provides a single meal; by teaching someone to fish, one provides food for a lifetime.

Description:
Set forth the basic theory, numerical calculations, and applications of linear time invariant and time-varying state model formulations of continuous and discrete time systems. This includes some transfer function matrix material when defined, along with some nonlinear material, e.g., linearization of a nonlinear state model. Develop analytic solutions of state models including the notion of the state transition matrix and the complete solution to the linear state model. In the time invariant case this includes an extensive eigenvalue-eigenvector discussion of the matrix exponential. Finally the course develops the analytic and numerical content of the critical concepts of controllability, observability, and stability. Students should be able to apply the material to determine the controllability, observability and stability of complex systems in state variable form. Depending on the progress, advanced topics such as state feedback control, output based observer, linear quadratic regulation, and model order reduction will also be covered.

1. Systems and state variables
2. State-space models of lumped linear systems
3. Linear algebra review
