【摘要】:針對永磁同步電機(jī)位置控制系統(tǒng)存在負(fù)載擾動情況下的控制精度低,響應(yīng)速度慢的問題,提出了一種基于終端滑模負(fù)載觀測器的反步控制方法。設(shè)計了基于非奇異終端滑模的負(fù)載觀測器,使觀測誤差在有限時間內(nèi)收斂,并將觀測值動態(tài)補(bǔ)償?shù)娇刂破髦?提高了系統(tǒng)的控制精度;基于非奇異終端滑模和反步法設(shè)計位置控制器,提高了系統(tǒng)狀態(tài)的收斂速度,增強(qiáng)了系統(tǒng)的魯棒性,通過Lyapunov穩(wěn)定性判定法證明了系統(tǒng)的穩(wěn)定性。仿真結(jié)果表明,設(shè)計的終端滑模負(fù)載觀測器能夠快速、準(zhǔn)確地估計出負(fù)載轉(zhuǎn)矩,位置控制器能有效實現(xiàn)系統(tǒng)位置的漸近跟蹤。
[Abstract]:In order to solve the problem of low control precision and slow response speed in the permanent magnet synchronous motor position control system under the condition of load disturbance, a backstepping control method based on terminal sliding mode load observer is proposed. A load observer based on non-singular terminal sliding mode is designed so that the observation error converges in finite time and the observation value is dynamically compensated to the controller to improve the control accuracy of the system. A position controller based on non-singular terminal sliding mode and backstepping method is designed, which improves the convergence speed of the system state and enhances the robustness of the system. The stability of the system is proved by Lyapunov stability judgement method. The simulation results show that the designed terminal sliding mode load observer can estimate the load torque quickly and accurately, and the position controller can effectively realize the asymptotic tracking of the position of the system.
