Deadbeat predictive current control for PMSM

In this paper a predictive current control for PMSM based on dead-beat algorithm is proposed, in the synchronous rotary frame, to improve the performance of current loop. Based on the mathematical model of PMSM the current controller calculated the expected voltage vector directly in terms of the current reference and feedback values, after that transforms the voltage vector into switch signals with SVPWM model. The robust predictive current control is introduced to decrease the sensitivity of system stability with the model parameters error. Simulation and experiment results show that the PMSM predictive current control scheme improves both the dynamic performance and steady-state precision of the current loop efficiently.
