Thoughts: The textbook problems did not help at all. 4 questions total. Each worth 10 points. Complete disaster. Had one on designing a PID controller. One on matching the root locus plot (with the zeros and poles) to the phase diagram. Explain which one would become unstable while increasing the gain or something. Third question had to do with (spaceX) designing a controller with no overshoot. Fourth question had us find stability, bibo stable, transfer function, design a controller with a 3x3 matrix. Don’t think I passed that exam.
