Abstract
Recently, from the viewpoint of global environmental protection, fuel consumption regulations for automobiles are required. To improve the fuel consumption, replacing gasoline engine with diesel engine and reduced-cylinder operation are considered. However, the vibration becomes large in these methods. Hydraulic active engine mount which cope with both fuel economy and ride comfort has been studied. Adaptive control which is generally used as a control method for an active engine mount cannot function well when the engine frequency varies. In this research, engine vibration suppression using model matching control method with characteristic transfer function matrix is aimed and its effectiveness is confirmed by basic experimental equipment. In addition, the combination of model matching control and adaptive control is considered.
