Super-twisting Sliding Mode Control for Asynchronous Motor Based on Flux Online Identification
摘要
Abstract
The problem of super-twisting sliding mode control for asynchronous motor based on flux online identi-fication is studied.In order to enhance the dynamic response performance of the system,an improved super-twist-ing sliding mode speed controller is designed for the asynchronous motor.To suppress the system chattering prob-lem caused by the high-frequency switching of the sign function in the algorithm,a variable exponent switching function is constructed.Furthermore,considering the influence of the inertia delay on the rotor flux,a flux online observer is designed to identify the rotor flux amplitude,which boosts the control accuracy and parameter robust-ness of the system.Numerical simulations and experimental results verify the feasibility and effectiveness of the pro-posed algorithm.关键词
