Kent Lundberg's Notes on Feedback Systems was used as the primary reference for 6.302 Feedback Systems for several years (at least 2004 to 2013).

His Become One with the Transistor was used as a supplementary reference in 6.301 Solid State Circuits.

He also provided recitation notes for 6.331 Advanced Circuit Techniques.

Supplementary Material

This material is for Notes on Feedback Systems: Old lecture videos, animations to demonstrate and clarify some of the concepts, and color versions of some of the figures that didn't print well. (The sections listed in parentheses refer to the accompanying reading in the notes.)

By Chapter:

1. Introduction
2. Prerequisites
3. Modeling and Responses
   • Video of Steady-State Error Demo (Section 3.5)
4. Stability
   • Video of F/A-22 Raptor instability (from NOVA's Battle of the X-Planes).
5. Root-Locus Method
6. Nyquist Criterion
   • Animation: a simple demonstration of Cauchy's Principle of the Angle (Section 6.2).
   • Animation: drawing a Nyquist diagram for L(s)=1/(s+1)³ with standard D-contour (Section 6.4.3).
   • Animation: drawing a Nyquist diagram from measured frequency-response data (Section 6.4.3).
   • Animation: drawing a Nyquist diagram for L(s)=(s+1)/(s²+1) with notched D-contour (Section 6.5).
7. Frequency-Domain Analysis
   • Animation: transformation of Nichols plot to closed-loop Bode plot for L(s)=1/s(s+1) (Section 7.2.2).
   • Animation: transformation of Nichols plot to closed-loop Bode plot for L(s)=10/s(s+1) (Section 7.2.2).
8. The Big Picture
   • Matlab .m script for Chapter 8 figures.
