Bode Diagram Frequency(rad/sec)
General Notch filter format (s/)2+2(s/u)s+1 (s/u)2+2(s/u)s+1) Using Notch Compensation Plant under study Requirements: Want to have good tracking, decent PM Draw physical system and OL transer function here
Compensation Scheme: Use lead compensation Phase Margin is Gain Margin is BW is
