| 摘 要： | 针对传统的直接转矩控制系统采用纯积分的电压模型作为磁链观测器，存在着误差积累以及直流偏移，导致电流和转矩的波动问题，提出了一种基于定子磁链的自适应全阶观测器的直接转矩控制系统，并实现了速度辨识。仿真实验表明：采用自适应磁链观测器具有较高的观测精度和较好的鲁棒性。

| Abstract: | In the traditional direct torque control system, pure integral voltage model is used as flux observer. There are error accumulation and direct current offset in this system, which cause the fluctuation of current and torque. A direct torque control system based on adaptive full--order flux observer is presented and speed identification is obtained. Simula- tion results show that adaptive flux observer is with higher accuracy and better robustness. |
