EE 154: Feedback Control Systems

Catalog Copy
EE154. Feedback Control Systems. W.  Analysis and design of continuous
 linear feedback control systems.  Essential principles and advantages
 of feedback. Design by root locus, frequency response, and state space
 methods and companions of these
 techniques. Applications. Prerequisite: Course 103. Enrollment limited
 to 30. P. Milanfar.

Explanation of Prerequisites.

EE 103 Signals and systems. To fully comprehend block diagrams for
 analysis and design, students must be well versed in both time and
 frequency domain analysis, know the difference between Fourier and
 Laplace transforms as well as their use and relation to the time
 domain, and understand transfer functions with both physical and
 unipulse response implications.

Required Skills to Pass the Course:

1. Find the input/output equation from given connected components equation.
2. Determine the stability of the input/output equation.
3. Produce and interpret a Bode diagram.
4. Determine the system type.
5. Produce and interpret a root locus.
6. Design a simple PID controller.

Core Topics (must be taught)
1. Review of Systems and signals, transfer functions
2. S-plane (effect of pole and zero locations.
3. Frequency response
4. Time domain (convolution, impulse and step response)
5. Interrelationships of the above
6. Block diagrams
7. manipulations
8. reduction and simplification
9. Stability
10. Routh criterion
11. Bode criterion
12. Nyquist criterion
13. System Type
14. Bode plots
15. Root locus
16. PID controllers

Optional Topics
1. System sensitivity
2. Design case studies
3. Digital control
4. State space

Comments on related concurrent courses:

EE 153 Digital Signal Processing. Difference equations and
 Z-transforms taught in 153 are a foundation for digital control
 systems. The block diagrams and frequency response of 154 help
 students in 153. Students can take 153 and 154 concurrently or in
 either order.
ENG 147 Computational Methods and Applications.  Methods are taught in
 ENG 147 and are very useful for examples in 154. Eng 147 should be
 taken prior or concurrently with 154, and should be lightly
 recommended but not required for 154.

Text 
Franklin, Powell, and Emami-Naeni, "Feedback Control of Dynamic
Systems" Prentice-Hall 4th ed. 2002. A too comprehensive classical
text that must be extensively edited and exised to keep the students
focused o the important topics, lest they get overwhelmed by the
voluminous detail.

Possible Alternate Texts:
Goodwin et al is an excellent text with a super supporting web site. We
 hope to try this text soon.

DiStefanolll, Stubbermd and Williams have a Schawm's Outline "Feedback and
 Control Systems" that is cheap and somewhat outdated and filled with
 examples. Unfortunately it is not quite up to the present text's quality.
