【Abstract】 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.更多还原
