基于滑模控制的异步电机全阶观测器研究
Study on Full Order Observer Based on Sliding Mode Control for Asynchronous Motor
摘要
Abstract
For the low speed stable operation and widening speed range of the vector control system of asynchronous motor based on the full order observer,an improved full order observer method based on sliding mode control for asynchronous motor was presented. The full order flux observer was used to estimate motor speed and rotor flux and improve the ability of carrying capacity at low speed. Simultaneously,the sliding mode controller was properly designed to widen the range of speed adjustment,as well as enhanced systemic robustness. Finally,the simulation model was built in Matlab,and the physical experiment platform was built in DSP28055. The simulation and experiment results show that the proposed control strategy broadens the speed range of the motor,improves the low speed load capacity,and verifies the feasibility of the method.关键词
