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

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. |
