Consider a system with open loop transfer function in unity feedback configuration 10 G(s) = s(s/1.4+1)(s/3+1) Ts+1 15) Design a lag compensator with unity gain of the form Ge so that the Phase BTs+1 Margin is > 40°. Since the addition of a lag compensator modifies the phase curve, we will add about 10° to the specified phase margin, to compensate for the modification of the phase curve. What should then be the new gain cross over frequency under these conditions? (in rad/sec)

Consider a system with open loop transfer function in unity feedback configuration 10 G(s) = s(s/1.4+1)(s/3+1) Ts+1 15) Design a lag compensator with unity gain of the form G. : so that the Phase BTs+1 Margin is > 40°. Since the addition of a lag compensator modifies the phase curve, we will add about 10° to the specified phase margin, to compensate for the modification of the phase curve. What should then be the new gain cross over frequency under these conditions? (in rad/sec)
