Speed Estimation Field-orientation-controlled Interior Permanent Magnet Synchronous Motor Drive Using High-frequency Signal Injection Technique

Year: 2025

Type: article

Abstract: A high-frequency signal injection technique was proposed for speed estimation in a fieldorientation-controlled (FOC) interior permanent magnet synchronous motor (IPMSM) drive.The decoupled FOC IPMSM drive based on the stator current and flux was established to achieve a maximum torque-to-current ratio, with stator current measurements obtained using Hall effect current sensors.On the basis of the linear control of the two-axis stator current and speed loops, a systematic controller parameter design was developed by the pole placement method.A high-frequency voltage signal was injected into the IPMSM, and the resulting highfrequency current response was utilized to estimate the rotor position.The estimated rotor position was then employed to enable the speed estimation of the FOC IPMSM drive.The MATLAB ® \Simulink toolbox was used to establish this simulation system, and all the control algorithms were realized with a TI 6713 digital signal processor and an F2812 microcontroller card to validate the proposed approach.Both simulation and experimental results confirmed the effectiveness of the proposed method.
