Abstract

This paper examines the improvement of the speed-sensorless vector control performance of an induction motor with a speed estimator using the self-tuning regulator (STR) control scheme. The proposed scheme, which consists of a recursive least squares algorithm and a PI control algorithm, increases the stability and improves the control performance in both the steady-state and transient state for both varying and constant speed references.

基于递推最小二乘算法的异步电动机无速度传感器矢量控制
本文研究了采用自整定调节器(STR)控制方案对带速度估计器的异步电动机无速度传感器矢量控制性能的改进。该方案由递推最小二乘算法和PI控制算法组成,提高了系统在变速和恒速参考下稳态和暂态的稳定性和控制性能。
