基于矩阵变换器的异步电机容错控制的研究

Research on induction motor fault-tolerant control based on matrix converter

矩阵变换器(MC)具有输入输出特性好、电力谐波低、体积小等优良特性,但研究学者发现MC在实际应用中并不能稳定、可靠地运行,因而提出了不同的控制策略来提高其运行稳定性。本文提出一种MC的容错控制方法,使MC—电机系统在出现故障的情况下依然能够稳定运行或者安全停车,并对MC的输出进行谐波分析。仿真实验验证了采用容错控制能够提高矩阵变换器的运行稳定性,证明了这一理论的正确性和可行性。

Matrix converter with input and output characteristics, low power harmonics, small size and excellent characteristics. But scholars have found that the matrix converter in reality can not be stable and reliable running, thus different control strategy are proposed to improve the stability of its run. In this paper, a fault-tolerant matrix converter controls method is proposed, so that it remains stable operation in the case of damaged normal, and the input and output of the matrix converter harmonic analysis. Through the analysis of the matrix converter input and output characteristics of the simulation results prove that the matrix converter can be stabled correctness and feasibility.
