摘要：

For the dual H-bridges fed two-phase hybrid stepper motor (HSM), two independent controllers are used to regulate two-phase currents separately, which has drawbacks such as complex hardware structure and large current ripple. A three-phase voltage source inverter (VSI) fed two-phase HSM drive topology model is established, and a strategy of using a predictive controller to adjust two-phase currents synchronously is proposed. Two typical predictive control strategies, the finite control set model predictive current control (FCS-MPCC) and deadbeat predictive current control (DPCC), were implemented. Firstly, a space voltage vector model was established under the unbalanced circuit structure. Secondly, voltage control set, current prediction model, and cost function was constructed to realize FCS-MPCC. Finally, the space vector pulse width modulation was improved to realize DPCC. Simulations and experimental results show that predictive controllers have good dynamic and static characteristics, current ripple is small, and the control algorithm is easy to be implemented. © 2021, Harbin University of Science and Technology Publication.
