Compensator is used to compensate the deficiency in the performance of plant.
A lead compensator is used to improve the transient response and the steady state response is partially improved.
A lag compensator is used to improve the steady state response and the transient response is partially improved.
If we need a better transient response we should choose lead compensator.
If we need a better steady state response we should choose lag compensator.
If we need both transient response and steady state response we should choose lead lag compensator.
