Abstract:
Sliding mode controller may be used as a nonlinear controller that alters the dynamic behavior using an interrupting control signal to drive the system along a cross-section of the systemâ€™s normal behavior. In this paper, a new topology of sliding mode controller is designed for a linear voltage regulator operating under nonlinear conditions. Control schematic diagrams and units developed in this paper for the gain and band width of the controller are obtained for voltage variation, model in accuracies and robustness in the load, to maintain a dynamic performance comparable to that obtained with current control techniques. The chattering effect of the controller is also taken into consideration. The results and performance of the proposed controller is verified using automated software including Simplorer 7 and Matlab (Simulink).
