| Abstract: | Through the establishment of quarter vehicle model and the application of optimal control theory, a LQG (Linear Quadratic Gaussian) controller of automobile active suspension was designed . A system simulation model based on Matlab/Simulink environment was built and used for simulation.Simulation results was compared with passive suspension.The simulation results demonstrated that the active suspension with a LQG controller could improve automobile riding comfort performance enormously. |
