Modeling and simulation of PWM based sliding mode voltage controller for Boost converter in continuous conduction mode

Abstract

SM control is a kind of nonlinear control which has been developed predominantly for the control of variable structure systems. Being a control method it has a high degree of flexibility in its design choices, the SM control method is relatively easy to implement as compared to other nonlinear control methods. The design procedure and mathematical modeling for the Boost Converter has been interpreted. In this paper the sliding coefficient for the controller has been selected based on fulfilling the hitting, existence and stability conditions. The controller equations for the selected bandwidth have been derived and modeled using MATLAB/SIMULINK.
