摘要：
Aiming at the control problem of electromech-anical systems with nonlinear, high sampling frequency and strong coupling characteristics, a control method based on explicit model prediction is proposed. Firstly, the mathematical model is established based on the three-phase asynchronous electromechanical coupling system. Then, the multi-parameter quadratic programming method is used to calculate the explicit optimal control rate of the AC motor system offline, and the control quantity corresponding to the current state is searched online. The experimental simulation results show that this strategy not only improves the running speed of the system but also solves the problem of excessive coupling of complex systems under the condition of ensuring stable and safe operation of the system.
