2. Become familiar with issues faced in sampling, digital data and discrete time systems.

3. Gain experience in designing digital controllers either by emulating continuous time compensators or by direct digital design using the Root Locus and Frequency Response methods. (EAC c)

4. Be given a brief introduction to digital filter design.

Prerequisites by Topic

Control Systems

Lecture Topics:
  • Introduction and Z Transforms
  • Sampling and Reconstruction
  • Open and Closed Loop Sampled Data Systems
  • Time Response and Stability
  • Frequency Response and Stability
  • Digital Control Design
  • Analog and Digital Filters
Class Schedule:

Meets for 3 hours of lecture and 1 hour of discussion each week for 10 weeks.
