摘要: 介绍了参数估计法(基于方脉冲函数与最小二乘法)应用于航空永磁直流电动机的虚拟测试系统原理.首先由参数法估计出电机的机电参数,然后通过电动机的机电参数与其多个物理量及特性之间的函数关系,得到相关的物理量和静、动态特性,并能进行故障检测与诊断.实现了该系统强大和完备的测试功能.

Abstract: Parameter estimation method (based on block pulse function and least square method) applicable to virtual test system of a permanent-magnet DC motor was discussed. Electromechanical parameters of the motor was obtained through parameter estimation. Physical parameters, dynamic and static characteristics of the motor were obtained from their function relations with the electromechanical parameters. Finally, fault detection and diagnosis were conducted. It was shown that the system possesses powerful and self-contained test functions.
