Sliding Mode Controller (SMC) Governed Speed Control of DC Motor

The sliding mode controller is one of best tool to analyze the second order dynamic system. This paper provides comparative study of control techniques of DC motor under loaded condition. The design of sliding mode control is based on the variable structure system (VSS).the trajectory path of the system depend on the control signal of SMC controller. The main objective of the controller is to reduce the settling time and peak overshoot of the system. Particularly, in robotics DC motor is used and it's very essential to control the speed under loaded condition. The SMC gives best performance in Linear and nonlinear of system. Stability of the system and performance of dc motor under load condition can easily analyzed by using sliding mode nonlinear control. The proposed system model simulate and developed in MATLAB.
