摘　　要：对于无位置传感器无刷直流电机(Brushless DC Motor,BDCM)的启动控制而言,其核心在于观测或估计电机定子绕组电感参数,并根据其与转子的位置关系来实现电机的正确启动。首先简要介绍电感法原理,并分析电感参数随转子位置变化的规律,然后制定基于电感变化规律的脉冲注入法控制策略,最后建立了一种基于Matlab/Simulink,Ansoft Simplorer和Ansoft Maxwell的多软件联合仿真模型,对提出的控制策略进行仿真验证,仿真结果准确可靠。The measurement or estimation of stator winding inductance parameter is essential for the startup control of the brushless DC motor. The motor can be started correctly according to the relationship between the rotor position and the parameter. The paper first briefly introduces the principles of inductive method, analyzes the change law of inductance parameters against rotor position, and then formulates the control strategy based on pulse injection method. Finally, co-simulation of Matlab/Simulink with Ansoft Simplorer and Ansoft Maxwell is carried out in line with the proposed control strategy. The simulation results are verified to be accurate and reliable.
