【摘要】：由于輪轂電機驅(qū)動的電動汽車的驅(qū)動系統(tǒng)安裝在輪轂處,使得汽車懸架系統(tǒng)簧下質(zhì)量增加,造成舒適性變差及電機軸承磨損嚴重等問題。基于上述現(xiàn)象,并綜合考慮控制回路的輸入時滯及參數(shù)攝動因素,研究了該類懸架系統(tǒng)的有限頻域動態(tài)輸出反饋振動控制策略。對比于傳統(tǒng)的時滯全頻域的H∞控制方法,該方法能在人體對振動較為敏感的頻段內(nèi)取得更好的干擾衰減,同時也能保證相關(guān)的時域硬約束。為了降低車身加速度在非簧載模態(tài)頻率處的奇異值,并減少傳遞到電機軸承上的力,考慮將動力吸振器(DVA)安裝在電機軸承座上。通過Lyapunov-Krasovskii泛函及廣義KYP引理,以線性矩陣不等式的形式推導(dǎo)出基于動態(tài)輸出反饋的控制準則。最后,通過一個數(shù)值實例驗證該方法在頻域及時域的有效性。
[Abstract]:Because the driving system of electric vehicle driven by hub motor is installed at the hub, the mass under spring of suspension system increases, which results in poor comfort and serious wear of motor bearing. Based on the above phenomena and considering the input time delay and parameter perturbation factors of the control loop, the dynamic output feedback vibration control strategy in finite frequency domain for this kind of suspension system is studied. Compared with the traditional H 鈭，
