永磁同步电动机的模型参考自适应速度控制

A Speed Controller of Permanent Magnet Synchronous Motor Using MRAC

本文介绍了一个基于DSP的PMSM自适应速度控制器，其使用了模型参考自适应方法．具有计算量小的特点，能实时辨识系统参数，采用自适应负载转矩观测器补偿负载转短扰动。仿真和实验表明本控制器在系统参数变化和负载转矩扰动的情况下具有良好的自适应能力。

A DSP-based adaptive speed regulator for PMSM is designed and implemented. The proposed adaptive control scheme is characterized by a reduced amount of computation and is based on the model reference adaptive control approach. The parameters related to load inertia and damping coefficient are estimated on-line by MRAC. An adaptive disturbance torque observer is employed to compensate the required load torque. Digital simulation and experimental results show the proposed controller has excellent adaptation capability under parameter variation and load torque disturbance.
