The paper is concerned with the optimisation of damping in a semi-active vibration isolation system for a driver's seat. The seat and the driver are modelled as a 2DOF system and a deterministic quality criterion - the root-mean-square (rms) value of the driver body acceleration is adopted. An assumption is made that the seat suspension has a semi-active actuator which allows for active adjustments of the damping force depending on the driver's mass and on external excitations. Computer simulations were employed to select the optimal passive damper for the specified driver's mass and the optimal damping function for the predetermined kinematic excitations coming from the base. The laws for damper control were formulated such that the accepted quality criterion be minimised.
