摘　　要：针对同步磁阻电机控制中因电感变化带来的系统稳定性及可靠性问题,提出一种基于离线电感参数更新的同步磁阻电机最大转矩电流比控制方法。首先设计了无铁氧体同步磁阻电机的最大转矩电流比控制方法,其次通过实验获得全工况下d、q电感参数生成离线电感参数表,并将其引入控制算法中,实现d、q轴电感的实时更新。实验结果表明,传统的最大转矩电流比算法引入实时更新的电感值后,能够快速响应由电流变化所引起的电感变化,及时调整系统控制参数,相较于传统的最大转矩电流比控制方法具有更快的动态响应能力和更小的稳态误差,提高了系统的稳定性和可靠性。To improve the stability and reliability of synchronous reluctance motor control by addressing inductance changes,a new maximum torque/current ratio control method based on offline inductance parameter update is proposed.First,the maximum torque/current ratio control method for the ferrite-free synchronous reluctance motor is designed.Second,an offline inductance parameter table is generated through experiments to obtain the d and q inductance parameters under all operating conditions,which is then introduced into the control algorithm to enable real-time updates of the d and q axis inductance.Experimental results show that the proposed algorithm responds quickly to inductance changes caused by current changes and adjusts system control parameters in a timely manner.Compared to the traditional maximum torque/current ratio control method,the proposed method offers faster dynamic response and smaller steady-state error,and improved the stability and reliability of the system.
