【摘要】:針對具有大加減速和系統(tǒng)參數(shù)不確定性的軸向移動系統(tǒng)振動主動控制問題,基于Lyapunov直接法、經(jīng)典反步控制和自適應(yīng)技術(shù),提出自適應(yīng)反步邊界控制算法對系統(tǒng)振動進(jìn)行主動控制,并以符號函數(shù)處理邊界擾動.同時,考慮不連續(xù)符號函數(shù)在工程上易引起輸入顫振,設(shè)計飽和函數(shù)替代控制器中符號函數(shù),以提升振動控制品質(zhì).所設(shè)計的控制算法能夠補償系統(tǒng)參數(shù)不確定性,確保閉環(huán)系統(tǒng)穩(wěn)定性.數(shù)字仿真結(jié)果驗證了所提出的控制算法的有效性.
[Abstract]:Aiming at the active vibration control problem of axial moving system with large deceleration and uncertain system parameters, the paper is based on Lyapunov direct method, classical backstepping control and adaptive technology. An adaptive backstepping boundary control algorithm is proposed to control the vibration of the system, and the symbolic function is used to deal with the boundary disturbance. At the same time, considering that the discontinuous symbol function is easy to cause the input flutter in engineering, the saturation function is designed to replace the symbol function in the controller to improve the vibration control quality. The proposed control algorithm can compensate for the uncertainty of the system parameters and ensure the stability of the closed loop system. The digital simulation results verify the effectiveness of the proposed control algorithm.
