Model-free Recursive Nonsingular Terminal Sliding Mode Control of PMSM Speed Loop Based on Fractional-order Extended Sliding Mode Disturbance Observer
摘要
Abstract
Aiming at the problems of parameter changes and external load disturbances in the speed loop of permanent magnet synchronous motors,a novel model-free recursive nonsingular terminal sliding mode control(MFRNTSMC)method for the speed loop based on the fractional order extended slid-ing mode disturbance observer is proposed in this study to improve the response speed and anti-dis-turbance capability of a speed control system.First,a novel ultra-local model of a permanent mag-net synchronous motor based on the traditional mathematical model is developed.Second,a model-free recursive nonsingular terminal sliding mode controller located in the speed loop is designed by combining the novel ultra-local model and the recursive nonsingular terminal sliding mode control theory;a fractional order extended sliding mode disturbance observer is designed,which not only accurately compensates the unknown portion of the system but also improves the anti-disturbance a-bility of the speed loop controller.Finally,the superiority of the proposed sliding mode control method is verified by comparing simulation and experiment results.关键词
