STATE-FEEDBACK CONTROL FOR PASSENGER RIDE DYNAMICS

An analytical investigation of a half-car model with passenger dynamic s, subjected to random road disturbance, is performed. Two different m ethods of defining the performance index for optimal controller design are proposed. Nondeterministic inputs are applied to simulate the roa d surface conditions more realistically. Results obtained illustrate t hat using an optimal state-feedback controller, with passenger acceler ation included in the performance index, would exhibit not only an imp roved passenger ride comfort, but also, a better road handling and sta bility.
