摘要
建立了内燃机整机振动多自由度主动控制系统模型 ,推导了内燃机整机振动全状态施控最优控制规律和部分状态施控次优控制规律 ;以 41 35型柴油机为例 ,用计算机模拟了全状态施控最优反馈控制和部分状态施控次优反馈控制系统的特性 ,并在一台 41 35型柴油机上进行了主动控制台架试验 。
A multiple freedoms vibration active control system is established for body vibration of I.C.engines in this paper.The optimum control law for the state feedback control and the suboptimum control law for the partial state feedback control are presented to meet the active control of the body vibration in I.C.engines.A 4135 diesel engine is used as a research model.By computer simulation,the properties of these control methods are studied.The experimental study for the active control of the body vibration in 4135 diesel engine is carried out.The results show that the active control for multiple freedoms vibration system could be successfully achieved by the partial state feedback control.
