EE Times Field Oriented Control
In this article, Dave compares Field Oriented Control with Trapezoidal control to run a BLDC motor.
This is Part 1 of a 3-part series exploring how Field Oriented Control (FOC) works. To assist with learning this technology, Dave compares FOC to current control of a brush DC motor, where the process is dissected into four discrete steps. The first step is to measure the current flowing in the motor.
In Part 2 of this series, Dave covers the 2nd step in the FOC process, which is to compare the measured currents to the desired currents, and generate error signals, which is the longest and fundamentally most important step in the process.
This is the last part of the series which covers the final two steps to do Field Oriented Control.
This article discusses the basics about how to apply Field Oriented Control techniques to an AC induction motor.
In order to do Field Oriented Control on a motor, you need to know the angle of the rotor flux with respect to the motor frame, and have real-time updates of this angle. One way to achieve this is to mount a position sensor on the motor shaft. But position sensors can be very expensive, and also decrease the reliability of the system. This article explores how to obtain the flux angle by monitoring the phase voltages and phase currents of the motor, without requiring a shaft sensor.
This article explores one specific sensorless algorithm from Texas Instruments, and discusses how it simplifies the process of using Field Oriented Control.
