Sliding mode control of uncertain parameter for a matrix rectifier

Abstract

The external uncertainties and disturbance affect the DC output of a matrix rectifier (MR) system. This paper presents a sliding mode control (SMC) of uncertain parameters for a MR. Adding a value of anti-voltage into the control function can effectively mitigate the chattering of the sliding motion. Besides, the method of calculating the minimum value of anti-voltage are presented, which can ensure better dynamic performance of a MR. Theoretical and experimental results are presented to verify the correctness and feasibility of the novel control scheme.
