摘要

永磁同步电机控制系统在实际应用中，复杂多变的工况对电机的响应需求是不同的。为了拓宽电机控制系统的调速范围，且满足系统对转矩响应能力和大转矩输出特性的要求，在弱磁控制策略的基础上引入过调制方法，将其应用于永磁同步电机控制系统，并进行仿真和实验研究。结果表明，相比于无过调制的弱磁控制策略，带过调制的弱磁控制策略能使系统在调速过程中充分利用直流母线电压，从而提高了转矩响应和大转矩输出能力，缩短了转速响应时间，同时电机的工作效率符合应用要求。

Abstract

To broaden the speed range of motor control system and meet the requirements of system for strong torque response capability and the large torque output characteristics, an overmodulation method is applied to PMSM control system based on the flux-weakening control strategy. The demand of the motor response is different in the complex and changeable operating condition. Simulations and experiments are carried out. The simulations and experimental results are analyzed. Compared to the flux-weakening control strategy without overmodulation, it is found that the introduction of overmodulation method can make the system take full advantage of DC bus voltage. The torque response and large torque output are improved, and the speed response time is reduced by using the proposed method. At the same time, the working efficiency of motor is in accordance with the application requirements.
