Deadbeat predictive current control of PMSM drives with an adaptive flux‐weakening controller

Abstract

Abstract In practical application, the motor speed may need to be greater than the rated speed, so field‐weakening control is required. However, the conventional flux‐weakening control requires much tuning work, because multiple PI controllers are used. In order to make the tuning work easier, this paper combines flux‐weakening control with deadbeat predictive current control (DPCC) to eliminate two PI controllers in current loop. In addition, this paper also proposes a speed adaptive flux‐weakening controller, which can further simplify the tuning work. The effectiveness of this method has been confirmed on a 2.2 kW surface permanent magnet synchronous motor (SPMSM) experimental platform.
