Abstract

This paper is concerned with an active control for suspension with preview of large–sized buses using fuzzy reasoning. The vehicle model is described by a nonlinear system with six degrees of freedom subject to excitations from road surface. The active control is divided into fuzzy and preview controls. The first is determined such that the mean squares of vertical and rotary accelerations of vehicle body are minimised under the constraint on suspension travels and tyre deflections. The second is determined by information of future road surface. The simulation results indicate that the proposed active control is satisfactory in the suspension performance.
