ECE 48300 - Digital Control Systems Analysis and Design


Typical Design Problems 1) Parameters in a difference equation model are estimated by the least-squared error method and the system is simulated 2) A controller (usually PLD) for a nonlinear system is designed and simulated. The use of MatLab is encouraged.

Catalog Description:

The course introduces feedback computer controlled systems, the components of digital control systems, and system models on the z-domain (z-transfer functions) and on the time domain (state variable representations). The objectives for system design and evaluation of system performance are considered. Various discrete-time controllers are designed including PID-controllers, state and output feedback controllers, and reconstruction of states using observers. The systems with the designed controllers are tested by simulations.
