Adaptive flux-weakening controller for IPMSM drives

2011 IEEE Energy Conversion Congress and Exposition, 2011
Voltage feed-back flux-weakening (FW) control scheme for vector-controlled Interior Permanent Magnet Synchronous Motor (IPMSM) drive systems is considered in this paper. The voltage controller is based on the difference between the amplitude of the reference voltage space vector and a proper limit value, related to the feeding inverter limitations, and

Flux-weakening control performance of partitioned stator switched flux PM machines

2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015
This paper first investigates the flux-weakening control performance of two types of partitioned stator-switched flux permanent-magnet (PM) (PS-SFPM) machines and then proposes a novel mechanical flux-weakening technique. The PS-SFPM machine topologies, operation principles, and flux-weakening control method are described. In addition, it is shown that

Flux-Weakening Control Method

2020
Reduced DC-link capacitance permanent magnet synchronous motor (PMSM) drives have many advantages, such as longer lifetime, reduced cost and higher power density. However, due to the DC-link voltage fluctuation, the DC-link voltage utilization rate and the torque ripples are two major issues in flux-weakening operation region.

Study on Flux-Weakening Control for PMSM

2011 Fourth International Symposium on Knowledge Acquisition and Modeling, 2011
Based on the mathematical model of Space Vector Control of permanent-magnet synchronous-motor(PMSM) and the analysis of flux-weakening control, a vector control simulation model of PMSM using flux-weakening control is built and some relevant individual modules are constructed, such as Flux-weakening control module, SVPWM generation module and so on.
