ABSTRACT:
A suspension system controller uses both linear and nonlinear relations to develop the suspension system state estimation. The linear components include (i) a component linearly related to the previous suspension system state estimation, (ii) a component linearly related to damping or actuator force in the suspension system, (iii) a component linearly related to error between the previously estimated relative suspension system state and measured relative system state and (iv) a component non-linearly related to error between the previously estimated relative system state, the linear and nonlinear components must all be stable, so that the estimated system state tends toward the actual system state. The controller controls the suspension system responsive to the suspension system state estimation.
