| 摘 要： | 为了实现异步电动机矢量系统的无速度传感器控制,本文给出了自适应全阶磁链观测器的无速度传感器控制策略,利用李雅普诺夫稳定性定理证明了观测器的稳定性,并推导出了转速自适应率。搭建了基于自适应全阶磁链观测器的异步电动机矢量控制系统的仿真模型和实验平台,实现了异步电动机的控制。实验结果表明该控制系统在较宽的范围内具有良好的动、静态性能。

Research on Speed Sensorless Vector Control for Asynchronous Motor |
| |
| Abstract: | In order to realize the induction motor vector control system without speed sensor , a speed sensorless control strategy is proposed based on adaptive full order flux observer. The stability of the observer is proved by using the Lyapunov stability theorem, and the adaptive speed rate is given. The simulation model and experimental platform of the vector control system based on the adaptive full order flux observer are built to control asynchronous motor. The simulation and experimental results show that the control system has good dynamic and static performance in a wide range. |
