Improved active disturbance rejection control strategy for space-vector-modulated matrix converter

Abstract

In this paper, an improved active disturbance rejection control (ADRC) strategy is proposed to solve the problem that the performance of the output side of the matrix converter (MC) is easily affected by the disturbance of the input side. According to the basic principle of the traditional ADRC, the non-linear feedback function is reconstructed, and the improved strategy is designed to solve the controller's dynamic buffeting. The experimental results show that the space-vector-modulated MC (SVM-MC) based on improved ADRC has good output performance in both steady-state conditions and dynamic disturbance conditions, and the output waveforms harmonic distortion is low.
