DIGITAL SIMULATION OF VECTOR CONTROL AND SLIP FREQUENCY CONTROL OF INDUCTION MOTOR

摘要

This paper describes the simulation of vector control system and slip frequency control system of induction motor. The principle of the vector control and the slip frequency control are explained and the maths model of induction motor with consideration of magnetic saturation effects is disscussed, followed by an algorithm to simulate various components of the systems in digital computer. The dynamic response of the system for the load disturbance and set-point variations have been studied, also, the results of the simulation showing the havior of field coordinates for such disturbances are given.
