摘    要:针对自抗扰控制(ADRC)中需要整定参数较多,且无明确物理意义,只能采取试凑法的问题,提出了线性ADRC的控制方法,并将其应用于永磁同步电机的速度环中。线性ADRC需调整的参数大大减少,调节过程得以简化,且减少了计算量,便于硬件控制器实现,控制效果却与非线性ADRC相当。通过仿真试验,与PI控制和ADRC进行比较,可得出线性ADRC克服了非线性ADRC其参数调整难度大的缺点,保留了其静动态性能和鲁棒性较好的优点。

关 键 词:永磁同步电机  调速器  线性自抗扰控制  参数整定

Abstract:A method of linear active-disturbance-rejection control(ADRC)is presented in this paper and is applied to the speed ring of permanent magnet synchronous motor(PMSM)to overcome the difficulties that many parameters in ADRC must be adjusted,the parameters have no physical meaning,and trial and error method depending on experience of an operator has to be used. The regulation process of parameters for the linear ADRC is simple and parameter’number and calculated amount are greatly reduced,so it is easy to realize the hardware controller,whose control effect is similar to the non-linear ADRC. The sim-ulation results of linear ADRC and PI control are compared. The results show that the linear ADRC has overcome the shortcom-ings of the non-linear ADRC whose parameters is difficult to be adjusted,but retained the non-linear ADRC’s advantages:good static/dynamic performance and robustness.
Keywords:motor  speed controller  linear active-disturbance-rejection control  parameter adjustment
