摘　　要：针对传统自抗扰控制器(ADRC)整定参数较多且整定困难的问题以及传统基于反电势的无感控制算法在低速下难以收敛,性能表现不佳的缺点,提出了一种基于自适应线性自抗扰控制器(ALADRC)的永磁同步电机(PMSM)无感控制方法。设计ALADRC,与磁链观测器进行结合,通过Softsign函数和实际转速设计自适应带宽函数对控制带宽进行自适应调节,使控制器抗干扰性能更强、参数调节更加简单、并使其适用于全转速段的应用场景。仿真及实验结果验证了所提方法的可行性和有效性。A novel permanent magnet synchronous motor(PMSM)control method is proposed by using adaptive linear active disturbance rejection controller(ALADRC)to overcome the weaknesses of traditional active disturbance rejetion controller(ADRC)which has numerous parameters that are difficult to tune and solve the problem of failing to converge in low speed performance of traditional Back-EMF based sensorless control methods.The ALADRC and flux observer are designed and combined together with the adoption of Softsign function and adaptive bandwidth function refer to actual speed.The proposed method has stronger interference resistance performance,simpler parameter tuning ability,and wider applicability to various complex scenarios.Simulation and experimental results verify the feasibility and ef-fectiveness of this method.
