In order to reduce low-frequency vehicle vibration, the development of semi-active control theory on hydraulic engine mounts has long been anticipated. However, because the changes in mount vibration characteristics introduce nonlinearity to the mathematical treatment, no successful study has been achieved. In this study, the variable orifice damping in a semi-active engine mount was approximated as a linear forcing device. This approach enabled us to use optimum regulator theory in obtaining the optimum control of orifice damping. This method was proved to be effective by a shaker test on an engine mass-mount model setup.
