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
