Abstract

For a servo plant with an integrator, analytical tuning formulas for phase lead compensators with both gain and phase margin specifications are derived in this paper. Comparing with other tuning methods, this method is simple with a short tuning time. Simulation results under two typical cases show that this method is general, too.
