Bode Plot Example: Question: A unity control feedback system has G(s) =80/s(s+2)(s+20). Draw the bode plot. Determine the gain margin and phase margin. Also determine gain cross-over frequency and phase cross-over frequency. Comment on the system stability using this Bode plot. Solution: Step 1: Arrange G(s)H(s)in time constant form as follows: Step 2: Identify factors […]![]()
