Prerequisites

ELEC_ENG 360 or equivalent

Description

Unified treatment of continuous and discrete time systems from a state-variable viewpoint; emphasis on linear systems. Concept of state, writing and solving state equations, controllability and observability, transform techniques (Fourier, Laplace, Z), stability, and Lyapunov's method.

REQUIRED TEXTS: Chen, C. T., Linear System Theory and Design, Oxford, 4th Edition, 2013 or International 4th edition, 2013. The international edition will probably have to be ordered from the UK. The two editions are not the same but that will be taken into account. You may encounter large price differences.

REFERENCE TEXTS: None

COURSE DIRECTOR: Prof. Arthur Butz

COURSE GOALS: Describe linear dynamic systems in terms of state variables and vector-matrix differential equations (continuous time) or difference equations (discrete time). The topics will include concept of linear space and linear operators, matrix algebra, eigenvalues and generalized eigenvectors, matrix functions, representation and solution of state-variable dynamic equations, controllability and observability of linear dynamic systems, and stability considerations
