lab manual
There is no homework but you might start doing lab exercises at home, since it is all about circuit simulators. It does not matter if you do them in 5Spice or TINA-TI.
You may want to install the circuit simulation software to your own computer. Below the links for it.
5Spice analog circuit simulator: download link
- 5Spice electronics components library for Physics 252: Library.zip (unzip/extract into the 'Library' directory of '5Spice Analysis' --> C:\Documents and Settings\All Users\Application Data\5Spice Analysis).
TINA-TI analog circuit simulator: download link.
- I personally like it more, it is easier to work with and it has noise analysis, which is missing in 5Spice.
The 5Spice electronics components libraries were provided in part by Alan Stummer (Dept. of Physics, University of Toronto).
Week 09
Lecture 09 - Feedback
- Theory of feedback
- PID controllers
lab manual
PID simulator
pid_dynamics.m
run it in Matlab as
S0 = .1; Sd = 1; tau = 10; Gp = -10; Gi = -2; Gd = 0; [t,S] = pid_dynamics(S0, Sd, tau, Gp, Gi, Gd);
