Q6) For the given Bode diagram, determine: a- The gain and the phase margins of that system. b-The gain and the phase cross over frequencies of the system. c- Check the system stability; give reasons for your answer. d- Calculate the gain should be added to the system to be having a gain margin of 20 dB, then calculate the new gain of the modified system. e-Draw the Bode diagram of the modified system. f- Calculate the parameters of a PID-controller for the modified system. Magnitude (dB) Phase (deg) 100 50 O -100 -150 -90 -135 -180 -270 To
