PROJECT TITLE :

Implementation of high-performance sensorless interior permanent-magnet synchronous motor Control Systems using a high-frequency injection technique

ABSTRACT :

This study proposes a high-performance sensorless interior permanent-magnet synchronous motor management system using a high-frequency injection technique. A replacement estimation technique that uses each the high-frequency d-axis current and q-axis current to estimate the rotor position is investigated. By using the proposed methodology, the hypothesis-synchronisation signal used in the traditional high-frequency injection technique will be eliminated. A one.25 kHz, 15 V, sinusoidal waveform voltage is injected into the d-axis synchronous frame of the motor and then the high-frequency d-axis and q-axis currents can be measured to work out the rotor position of the motor. In addition, a replacement compensation methodology is developed to reduce the estimation position error as a result of of the mutual inductance and saturation effect of the motor. By using this new methodology, the estimated rotor-position error is at intervals ±a pair of electrical degrees. A digital signal processor, TMS-320-F2812, is used because the estimating and control centre. The experimental results show that the proposed methodology can be applied in each a sensorless speed Control System and a sensorless position Control System. The sensorless speed management system has quick response, sensible load disturbance response and sensible tracking response.
