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.
