## EECS 410 - System Theory

**CATALOG 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, 4^{th} Edition, 2013

**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
