Abstract：A genetic-particle swarm optimization algorithm was proposed to optimize the control rules of the active suspension.Simulation study on the air suspension systems is carried out using Matlab/Simulink， and compared with traditional passive suspension in the performance comparison and analysis. Simulation results show that optimal control of the active suspension based on improved genetic algorithm can effectively improve vehicle ride comfort and handling stability.

Key words：Linear Quadratic Regulator ; active suspension; improved genetic algorithm; optimal design

懸架是指連接車(chē)身和車(chē)輪間的一切傳力連接設(shè)備和裝置的總稱(chēng)，它把車(chē)體和車(chē)軸連接起來(lái)，使他們之間具有一定的彈性[1]。（剩余4402字）
