Sign in to UnlockThe system is to be compensated such that its gain-crossover frequency becomes same as its uncompensated phase-crossover frequency and provides a 45° phase margin. To achieve this, one may use
A lag compensator that provides an attenuation of 20 dB and a phase lag of 45° at the frequency of rad/s
A lead compensator that provides an amplification of 20 dB and a phase lead of 45° at the frequency of 3 rad/s
A lag-lead compensator that provides an amplification of 20 dB and a phase lag of 45° at the frequency of rad/s
A lag-lead compensator that provides an attenuation of 20 dB and a phase lag of 45° at the frequency of 3 rad/s
