DSP based implementation of high performance control for induction motor drive [articol]

Abstract

Amongst many control techniques developed and used for induction motor drives, Flux or Field oriented control is probably the most popular control method used for high-performance induction motor applications. The field oriented control algorithm involves heavy mathematical computations and therefore its implementation requires a high execution speed processor/controller to meet all practical system demands. However, the inherent computational power of the Digital Signal Processors (DSP) permits very fast computations. It provides user an easy way to implement various control techniques of induction motor drives for real time simulink model. In this paper, a simulation model of a current controlled, voltage source inverter fed, rotor flux based indirect field oriented drive system for an induction motor is developed in MATLAB environment with simulink and its performance is tested by implementing it on a tailor made experimental setup of 1 HP induction motor and DSP controller board-DS1202. The test results of the induction motor drive are studied for various operating conditions.
