中文摘要:

基于线性自抗扰控制 ( linear active disturbance rejection controller, LADRC) 在永磁同步电机 ( permanent magnet synchronous motor, PMSM)转速、电流复合控制中无法应对 q 轴电流突变和参数整定存在缺陷,提出一种改进的自抗扰控制器。首先,分析常规 LADRC 在转速、电流复合控制的设计方法,并对其核心参数进行剖析。其次,基于常规 LADRC 用最速控制综合函数(fhan)代替比例微分(the proportion of differential, PD)进行控制律设计,提高系统控制性能并优化参数配置方式;同时基于该函数特性,设计电流外环控制器,利用电流偏差反馈算法对 q 轴电流进行限幅控制,避免电流冲击过大损伤硬件。通过搭建实验平台测试,实验结果显示改进的 LADRC 能有效应对 q 轴电流冲击,同时具有与传统 LADRC 相当的抗扰能力,并且对扰动的瞬态响应时间缩短 20 ms,表明改进的 LADRC 具有更高的安全性能和良好的抗扰能力。

英文摘要:

Based on the fact that linear active disturbance rejection controller (LADRC) cannot cope with q-axis current mutation and parameter setting defects in the compound control of speed and current of permanent magnet synchronous motor (PMSM), an improved ADRC is proposed. Firstly, the design method of conventional LADRC in the compound control of speed and current is analyzed. Secondly, based on the conventional LADRC, the fastest control synthesis function (fhan) is used to replace the proportion of differential (PD) to design the control law, improve the system control performance and optimize the parameter configuration mode. At the same time, based on the function characteristics, the current outer loop controller is designed, and the current deviation feedback algorithm is used to limit the q-axis current, so as to avoid excessive current impact damaging the hardware. Through the establishment of the experimental platform, the experimental results show that the improved LADRC can effectively deal with the q-axis current impact, which has the same anti-interference ability as the traditional LADRC, and reduces the transient response time of disturbance by 20 ms. It shows that the improved LADRC has higher safety performance and good anti-interference ability.
