WebPhase-lead compensators can often be used to improve the stability of feedback control systems with a small gain margin or with time delays, because they raise the phase between their zero and their pole. Lag compensators are mainly used to raise the lower-frequency gain. • Time-domain differential equation (14.29) • Lead and lag compensators are used quite extensively in control. A lead compensator can increase the stability or speed of reponse of a system; a lag compensator can reduce (but not eliminate) the steady-state error.
