Abstract :
This paper addresses the design of sliding mode controller for permanent magnet stepper motor. The control scheme has been proposed since stepper motor has a poor response in open-loop operation, highly nonlinear plant and load torque perturbation and parameter uncertainties are also a common occurrence. The controller is designed based on differentially flat properties of stepper motor. The simulation is performed by applying various types of disturbance and parameter uncertainties conditions to evaluate the performance and the robustness of the controller.
