摘要

为弥补路面检测车车身振动位移所导致的图像偏移，提出了设计新型主动悬架系统来抑制车身振动位移方法。根据极小值原理推导了新型主动悬架LQG控制规律，利用Matlab软件仿真分析了被动悬架、传统主动悬架LQG控制器和新型主动悬架LQG控制器对图像偏移量补偿的效果。仿真结果表明，新型主动悬架LQG控制器对图像偏移量进行补偿的效果最好，优于电子稳像技术所取得的效果。

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.
