Homework 3
Effects of Feedback, PID Control
1. FPE 4.1
In part (b)
replace the words "minimize the system error r-y" by "minimize
the system output y". You are
essentially minimizing the system error, when the reference signal is zero (r =
0).
2. FPE 4.4
In part (d),
also assume beta = 1 when comparing magnitude (log scale) vs. frequency plots
(linear scale).
3. FPE 4.40
