Abstract: The present paper aims to designing the best controller of the servo motor. Servo motors feature a motion profile, which is a set of instructions programmed into the controller that defines the servo motor operation in terms of time, position, and velocity based on compensator modern control system. The control method is used to determine the gains of the controllers to apply the lead compensator The transfer equation of control system with required controller gains is established. The transfer functions for the servo motor system is obtained based on automatic control principles. The lead compensator for open loop is drawn and then gain margin values is. Finally the step responses of the closed loop system with servo motor system controller were drawn. The simulation results have proven the effectiveness of adding a lead compensator to a servomotor system on the overall gain margin value which is settable for the system under control.
