1.4 Sensorless FOC on PMSM using ZS/MT Hybrid Estimator
This example application shows how to control the Permanent Magnet Synchronous Motor (PMSM) with ZS/MT Hybrid Estimator based Field Oriented Control (FOC) on a PIC32MK Micro-controller.
Description
Permanent Magnet Synchronous Motor (PMSM) is controlled using Field Oriented Control (FOC). Rotor position and speed is determined using a hybrid estimator with high frequency injection (ZS/MT) for low speed and back EMF observer with PLL estimator for high speed control. Motor start/stop operation is controlled by the switch and motor speed can be changed by the on-board potentiometer. Waveforms and variables can be monitored run time using X2CScope.
Key features enabled in this project are:
- Dual shunt current measurement
- Speed control loop
- Hybrid ZS/MT
