摘　　要：航空无刷电机对转矩脉动的要求高,现有控制方法对限流控制对占空比有限制工况时,存在精度低的问题。本文分析了相电流限流控制策略下采用传统换相角模式下对电机输出转矩的损失原理,并提出一种在限流控制下的偏转角换相策略。通过仿真对比和试验测试,验证了该优化策略的有效性。Aviation brushless motors have high requirements for torque ripple,and the existing control methods have the problem of low accuracy when the duty cycle is limited by the current limiting control.This paper analyzes the loss principle of the motor output torque under the traditional commutation angle mode under the phase current limiting control strategy,and proposes a deflection angle commutation strategy under the current limiting control.The effectiveness of the optimized strategy is verified through simulation comparison and practical tests.
