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

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.

Recent Achievements in the Control of Interior Permanent-Magnet Synchronous Machine Drives: A Comprehensive Overview of the State of the Art

“…Also, a PDBCC method is introduced in [175], which can be used for IPMSM drives with very highly rated electrical frequencies and with limited sampling to fundamental frequency ratios. A FW control method based on PDBCC for an IPMSM is introduced in [179]. A PDBTC approach is introduced for IPMSMs in [176].…”

Speed Stability and Anti-Disturbance Performance Improvement of an Interior Permanent Magnet Synchronous Motor for Electric Vehicles

“…Simultaneously, the anti-disturbance performance of the PMSM plays a pivotal role in ensuring rapid response capability and stability of electric vehicles [3]. Building upon the development of nonlinear control theory, various approaches such as adaptive control, fuzzy neural network control and predictive control have been employed to address the speed regulation and anti-disturbance performance of the PMSM [4][5][6][7]. However, the implementation of the nonlinear control theory through computer programs necessitates high-speed computing performance from the hardware controller.…”

A sliding mode‐based single‐loop control strategy for permanent magnet synchronous motor drives

“…Field-oriented control (FOC) with a cascade structure is widely used in PMSM drives, where the outer speed loop and the two inner current loops are often implemented by conventional proportional-integral (PI) controllers [7,8]. The PI controllers may show slow response and high sensitivity to motor parameter variation at various operating conditions [9,10]. Thus, the PMSM drives may not achieve high dynamic performance and robustness with conventional controllers that possibly lack the ability to deal with unknown disturbances [11].…”
