AN ACTIVE SUSPENSION FOR A VEHICLE TRAVELLING ON FLEXIBLE BEAMS WITH AN IRREGULAR SURFACE

An active suspension design for a model vehicle travelling on a flexible beam with an irregular surface is presented. Stochastic optimal control theory is applied to the determination of an active control to the vehicle-beam system. The vehicle is modelled by a set of four linear differential equations subject to the beam deflection. The beam deflection is expressed as a linear combination of modal functions by using modal analysis. The state variables of the vehicle-beam system are estimated by using a Kalman filter with noisy measurements as inputs, and the active control is determined by minimizing the given performance index. The numerical example shows the effectiveness of the proposed approach. (A)
