Abstract： To compensate image excursions casued by vibration displacements of vehicle bodies, the method of designing a new type of active suspension systems is proposed. A LQG control law for this new type of active suspensions is derived with theory of minimum principle. By utilizing numerical results generated by Matlab that compensation effects for image excursions which are achieved by a passive suspension, a LQG controller used in traditional active suspensions and a LQG controller used in this new type of active suspensions are analysed. The results show that the LQG controller used in this new type of active suspensions performs best in compensating image excursions and achieves higher imaging-stability precision than the electronic image stabilization method.
