Based on the electromechanical coupling dynamics model of an electromechanical integrated toroidal transmission, the velocity transfer function of the transmission is obtained, and the state space expression of the system after the addition is derived. Considering the actual engineering requirements of the system, an optimal control theory model , The optimal control law is obtained, and the Riccati matrix equation is solved to obtain the feedback gain matrix. The Matlab simulation software simulates the tracking response and the optimal control input, and obviously improves the dynamic performance of the system, and realizes the proportional integral PI) control and optimal control.The results of this study are of guiding significance for the practical application of this type of transmission.
