A Sliding Mode Controller with cascaded control technique for DC to DC boost converter

In this paper, the Sliding Mode Controller cascaded with PI voltage controller for DC to DC Boost converter is discussed. General design issues of Sliding Mode Controller for boost converter are discussed and the need of cascade controller is established. The cascade control consists of voltage controller which is a PI controller and non-singular terminal sliding mode controller. The performance of conventional PI controller and non-singular terminal sliding mode controller for current control is tested for reference disturbance, line disturbance and load disturbance conditions. The simulations for above conditions are carried out in MATLAB/Simulink environment. The simulation results are presented to validate the effectiveness of proposed system.
