摘要
针对永磁同步电机(permanent magnet synchronous motor,PMSM)普通滑模控制存在的系统响应速度慢、存在抖振现象等问题,提出一种扰动观测的模糊全局快速终端滑模控制(global fast terminal sliding mode control,GFTSMC)策略。设计全局快速终端滑模控制器以提高系统的响应速度和抗干扰能力,结合控制系统状态设计模糊控制规则实时调整速度控制器中的参数,在不影响系统收敛速度的条件下抑制抖振;设计Luenberger扰动观测器,将扰动估计值反馈至PMSM控制器中,削弱扰动对PMSM控制系统的影响。搭建PMSM控制试验平台对提出的控制策略进行试验验证。试验结果表明,Luenberger扰动观测器能够有效地估计扰动实际值扰动观测的,PMSM GFTSMC策略能够提高电机的响应速度和抗干扰能力抑制滑模控制中的抖振现象,增强系统的鲁棒性。
Aiming at the problems of slow response and chattering in the general sliding mode control system of the permanent magnet synchronous motor(PMSM),a fuzzy global fast terminal sliding mode control(GFTSMC)strategy with disturbance observation is proposed.Firstly,a global fast terminal sliding mode controller is designed to improve the response speed and anti-interference ability of the system.Secondly,the fuzzy control rules are designed based on the state of the control system to adjust the parameters of the speed controller in real time,so as to suppress chattering without affecting the convergence speed of the system.Thirdly,the Luenberger disturbance observer is designed to feedback the estimated disturbance values to the PMSM controller to weaken the influence of disturbance on the PMSM control system.Finally,a PMSM control test platform is built to verify the proposed control strategy.The test results show that the Luenberger disturbance observer can effectively estimate the actual value of the disturbance,and the fuzzy GFTSMC strategy with disturbance observation for PMSM can improve the response speed and anti-interference ability of the motor,suppress the chattering phenomenon in the sliding mode control,and enhance the robustness of the system.
