An Adaptive Sliding Mode Control Algorithm for Boost DC-DC Converter of FCHEVs

Abstract

In this paper, an adaptive sliding mode control (ASMC) strategy is developed for boost DC-DC converter with uncertainty of measurement, load and battery resistance. The error of load and battery resistance caused by the change of load and battery resistance is estimated by using the adaptive rule. Considering the uncertainty and disturbance of load and measurement of sensor, an adaptive sliding mode nonlinear surface is proposed to ensure the transient response and robustness of the system. Simulation results show that, compared with PID method, the output voltage trajectory can track the reference voltage, and the output voltage response is good.
