| Abstract: | Based on the electromechanical coupled dynamic model of the novel electromechanical integrated drive system, the speed transfer function was obtained, and state space express of the system with regulator was derived. Considering the requirement of engineering practice, the theoretical model of optimal control was build, and the optimal control was obtained. The Riccati matrix equation was solved, the feedback gain matrix was get, and the tracking response and optimal control input were simulated with Matlab software, the dynamic performance was greatly improved, the combine of PI regulator and optimal control was achieved. The results offer meaningful instruction for the practical application of the novel drive system. |
