So the sliding mode variable structure controller was discussed, which has strong robustness against the disturbance, and the chattering phenomenon inherited from vsc was taken advantage to regular valve vibration for the purpose of avoiding coagulation on it, while precision of level control can be almost unaffected. but for the reason of control limitation, especially the acceleration insufficiency, the continuous time quasi - sliding mode vsc for one class of controllable system, as the substitution of ideal sliding mode control system, which was impossible to implemented, was researched, including the three essentials, reaching condition in particular, and the chattering ex - pression was given. furthermore, the effect to quasi - sliding mode motion and chatter - ing expression by extent disturbance was also analyzed
由於控制量相對受限制，並且主要體現在控制量加速不足方面，無法實現理想的滑模變結構控制，因此本文研究了一類能控系統在這種情況下的連續系統準滑模變結構控制，包括變結構控制三要素，尤其是到達條件；並且針對塞棒掛渣問題，給出了該情況下抖振的表達式；魯棒性方面，分析了外界擾動對準滑模運動的影響，並且給出了外擾作用下抖振的表達式。 -
The results of the experiments have showed that the vibration of the head and the buttock mainly take place in the frequency of 0. 5 ~ 20hz, the vibration acceleration of the passenger ' s head on the high - level sleeper bus at highway does not exceed 1. 20 m / s2, the buttock ' s vibration acceleration is not more than 1. 00m / s2, however the acceleration of the legs " vibration is less than 0. 50m / s2. the vibration experiments of trains were done on the hard and soft berths in the mountain diverged line and the plain main railway, the data showed that the vibration of the passenger ' s head and pelvis mainly took place in the frequency of 0. 5 - 15hz, under this range, the acceleration of head ' s vibration do n ' t exceed 0. 80m / s2, the but tock ' s vibration acceleration is not more than 0. 40m / s, the legs " vibration acceleration is less than 0. 30m / s
數據分析表明，頭部和臀部振動主要發生在0 . 5hz 20hz ，高檔公路臥鋪客車在高速公路上，頭部振動加速度值一般不超過1 . 20m s ~ 2 ，臀部振動加速度值一般在1 . 00m s ~ 2以下，而腿部振動加速度值一般在0 . 50m s ~ 2以下；鐵路臥鋪客車臥姿乘客振動試驗分別在山區支線和平原干線上運行的硬臥及軟臥臥鋪進行，數據分析表明，頭部和臀部振動也主要發生在0 . 5 15hz ；平原干線的鐵路軟臥，頭部振動加速度不超過0 . 80m s ~ 2 ，臀部振動加速度值不超過0 . 40m s ~ 2 ，而腿部振動加速度值則在0 . 30m s ~ 2以下。
