【Abstract】 In order to solve the problem that it is difficult to accurately measure the real state of the system, a quarter vehicle active suspension model was established by using the dynamic equation and state equation, and the optimal control theory was used to establish the optimal control active suspension model. The optimal control model of active suspension was compared with the full dimension state observation model of active suspension by MATLAB/Simulink simulation analysis. The simulation results show that the state feedback system with full order state observer of quarter vehicle optimal control active suspension is closer to the real state of the system, more accurate and reliable.更多还原
