| Abstract: | A 1/2 car model and a road input model were established based on the optimal control theory which was used to design a LQG controller of automobile active suspension. A system simulation model based on Matlab/Simulink environment was built and used for simulation. Four performance indexes, body acceleration, pitch angle acceleration, suspension dynamic travel and tire dynamic deflection, were compared. The simulation results demonstrated that the active suspension with a LQG controller could improve automobile riding comfort performance enormously. |
