<p>The conventional proportional-integral current regulator in the synchronous reference frame has limited performance in ultra-high-speed (UHS) motor drives. The complex vector current regulator can theoretically achieve ultra-high-speed and low carrier ratio. However, it still has the problem of poor disturbance rejection performance. To solve this problem, active resistance compensation is necessary. This paper proposes an enhanced digital current regulator based on predictive current active damping (PCAD). By predicting the feedback current, it improves the characteristic of the conventional active damping (CAD) method. The frequency response shows that the disturbance rejection performance of PCAD is better than CAD under similar noise suppression conditions. For UHS applications, the impact of inductance mismatch on the current controller is significant, while the impact of resistance mismatch is very limited. To further improve the current dynamic response capability, an inductance estimator is designed in the current prediction scheme based on the extended state observer. The estimated inductance is used to correct the current controller, which can reduce the current overshoot and settling time caused by inductance mismatch. Simulation and experiment results have been carried out to verify the superiority of the proposed method in terms of dynamic response and parameter robustness.</p>
