摘要
应用于航空领域的无传感器无刷直流电机需具有控制简单、运行效率高、调速性能好等特性。为满足这些特性要求,本文设计了一种基于DSP的无传感器无刷直流电机控制策略。该控制策略采用双闭环控制原理和无传感器转子位置检测方法,改进了电机启动方式;同时采用软件实现实时的相位补偿,设计了电机控制程序。最后通过MATLAB/Simulink平台仿真和实物综合调试,验证了所设计控制策略的有效性和实用性。
Sensorless brushless DC motor(BLDCM)used in aeronautical field needs the characteristics of simple control,high efficiency and good speed control performance.In order to meet the above characteristics requirements,a control strategy based on DSP is designed in this paper.The control strategy,which adopts the double closed-loop control principle and the sensorless rotor position detection method,can improve the starting mode of the motor;and simultaneously the real-time phase compensation can be realized by software,and the control program is designed.Finally,a simulation model is built on MATLAB/Simulink platform to verify the effectiveness and practicability of the designed control strategy.
