摘 要:In this article, a cooperative control combining deadbeat predictive control (DBPC) and state error port-controlled Hamiltonian (EPCH) method is presented for permanent magnet synchronous motor drives. This effective combination is achieved by a cooperation scheme based on the error function. First, the DBPC is introduced to provide a fast dynamic response, and the state EPCH method based on the loss model is constructed to get good steady-state performance and high efficiency. After that, to combine the advantages of both controllers, the improved sigmoid function based on real-time position error is designed as a cooperative scheme. Each control method can be utilised effectively within the corresponding range. Meanwhile, the switching process is continuous and smooth without unnecessary chattering. Thus, the proposed method not only solves the contradiction between dynamic and steady performance but also optimises energy consumption. Finally, the proposed method is verified experimentally. The results show that the motor control system based on the proposed method has fast dynamic transient response and good steady-state performance with high efficiency.
