Research of optimal control for electromechanical integrated toroidal drive with regulator

Based on the electromechanical coupled dynamic model of a generic electromechanical integrated drive system,the speed transfer function was obtained,and the state space express of the system with a regulator was derived. Considering the requirement of engineering practice,the theoretical model of optimal control was built,and the optimal control rule was obtained. The Riccati matrix equation was solved,the feedback gain matrix was acquired,and the tracking response and optimal control input were simulated with Matlab software. Finally,the dynamic performance was greatly improved,and the combination of proportion integration (PI) regulator and optimal control was achieved. The results offer meaningful instruction for the practical application of the generic drive system.
