This paper proposes an auto-tuning flux-weakening control for an IPMSM drive system. A predictive controller is implemented to enhance the dynamic responses of the proposed drive system, which yields improved overall transient responses, superior load responses, and good tracking responses. In addition, an on-line, auto-tuning flux-weakening control is implemented to control the IPMSM drive system...
This paper proposes a sensorless IPMSM position control system based on a high frequency injection method. The proposed method uses 12-bit low resolution A/D converters to covert the stator currents of the IPMSM. In addition, a 0.67kHz injection voltage, which has a 30 V amplitude, is used. By measuring the stator currents, the injection current components related to the injection voltage can be obtained...
This paper proposes the predictive controller design for a sensorless interior permanent magnet synchronous motor drive system. The predictive controllers include a current-loop predictive controller and a speed-loop predictive controller. By using the proposed control algorithms, the closed-loop sensorless interior permanent magnet synchronous motor drive system can achieve fast transient responses,...
