摘 要：This article presents an adaptive optimal control method for a semi-active suspension *** model of the suspension system is built,in which the components of uncertain parameters and exogenous disturbance are *** adaptive optimal control law consists of the sum of the optimal control component and the adaptive control ***,the optimal control law is designed for the model of the suspension system after ignoring the components of uncertain parameters and exogenous disturbance caused by the road *** optimal control law expresses the desired dynamic characteristics of the suspension ***,the adaptive component is designed with the purpose of compensating for the effects caused by uncertain parameters and exogenous disturbance caused by the road surface;the adaptive component has adaptive parameter rules to estimate uncertain parameters and exogenous *** exogenous disturbances are eliminated,the system responds with an optimal controller *** separating theoretically the dynamic of a semi-active suspension system,this solution allows the design of two separate controllers easily and has reduced the computational burden and the use of too many tools,thus allowing for more convenient hardware *** simulation results also show the effectiveness of damping oscillations of the proposed solution in this article.
