基于扩张状态观测器的异步电机反步EPH控制
Backstepping EPH Control of Induction Motor Based on Extended State Observer
摘要
Abstract
A backstepping error port-controlled Hamiltonian(EPH)controller based on a novel extended state observer(ESO)was designed to address the issues of insufficient rotor flux observation accuracy and slow system dynamic response in induction motor speed control.Firstly,an extended state observer was used to observe the rotor flux,expanding the change in rotor resistance in the model to a new state to improve the accuracy of rotor flux observation.Secondly,using the backstepping control method to obtain the balance point of the stator current of the EPH controller,designing a backstepping EPH controller can effectively improve the dynamic response ability of the EPH control.The experimental results demonstrate that the designed controller has better stability performance and faster response speed compared to the EPH controller.关键词
