OPTIMISATION AND PERFORMACE ENHANCEMENT OF ACTIVE SUSPENSION FOR AUTOMOBILE UNDER INTEGRATED STRUCTURE-CONTROL DESIGN

摘要：

The development of modern design concept has made people not be satisfied with designing a controller only when system or structure existed could not measure up the performances. It is leading people to consider the integrated problems of structure/controller at the beginning of the system or structure designing. Because the traditional design method of a vehicle active suspension system always design control parameters following structure parameters and it can not obtain the global optimal performances for the system, this paper presents an approach to design the parameters of the active suspension system by integrating its structure and control parameters based on simulated annealing algorithm and LQR control scheme. The effectiveness of the proposed integrated optimum method to improve ride comfort was proved by theory analysis, simulation and experimental results.
