| Abstract: | In this paper, an approach is presented to design the parameters of the vehicle semi active suspension system by integrating its structure and control parameters based on the genetic algorithm and LQG control.In the traditional design method of the system, control parameters is designed following structure parameters,and the global optimum performances of the system can not be achieved. Simulation results show that the proposed integrated optimization method is very effective in improving the riding performance and security of the vehicle. |
