Abstract

Time delays are inherent in plants leading undesired system performance including instability. A new approach of lead compensator design using Lambert W function for time delay systems is presented in this paper. This approach is helpful for the control of SRV02(Rotary Servo) plant by regulating speed of the DC motor in presence of time delays. Also proportional-plus velocity control for DC motors to regulate angular velocity is extended to proportional-plus integral plus velocity (PIV) control using Lambert W function approach. The design of compensator and controller has been done based on eigen value assignment method. The simulation results of proposed methods have been compared with smith predictor approach.
