Model predictive and sliding mode control of a boost converter

Abstract:

This paper presents a comparative study between two control strategies based on the sliding mode control theory applied to a switched DC-DC Boost converter. A master-slave control structure is applied to the converter such that the inner control loop is a sliding mode current controller and the outer voltage controller is designed according to what follows. First a Proportional-Integral compensator (PI) is proposed and second, a Model Predictive Controller (MPC) is used aiming an improved performance. The control strategies are validated on the nonlinear hybrid model in a simulation study. Tracking and disturbance rejection tests are performed in order to show the robustness of the controllers. ©2008 IEEE.
