Microcomputer for vector control of PWM VSI-fed induction motor

Abstract

The realization of a single-processor system for indirect field-oriented control of a voltage source inverter fed standard squirrel cage induction motor (IM) is described. The whole digital control structure, i.e. speed and current control, including PWM, is realized on an MC 68000 microprocessor. In addition to the algorithm, experimental results are presented.<>
