This paper presents a control synthesis method for a class of semi-active seat suspension systems with input time delay, parameter uncertainties and actuator saturation. A vertical vibration model of human body is employed and put together with the plant of the seat suspension system in order to gain a better insight of the control performances. The H∞ performance is used to measure ride comfort so that more general road disturbances can be considered. By defining a Lyapunov functional and… CONTINUE READING
