Title:
Controlling 3-Phase AC Induction Motors Using the PIC18F4431
Name:
AN900
Date:

Description:
This application note describes how the PIC18F4431 may be used to control an ACIM using open and closed-loop V/f control strategies. The application code is built incrementally and demonstrates the following control methods: 1. Voltage-frequency (V/f) control 2. Voltage-frequency control with current feedback 3. Voltage-frequency control with velocity feedback and PID control The PIC18F4431 incorporates a set of innovative peripherals, designed especially for motor control applications. The utility of these peripherals is demonstrated in both open and closed-loop three-phase ACIM motor applications. It is assumed that the reader is already familiar with the theory and nomenclature of AC induction motors. For an excellent introduction to the basic concepts of induction motors control, please refer to Microchip?s application note AN887, ?AC Induction Motor Fundamentals? (DS00887).
