Industrial implementations of control algorithms for voltage inverters supplying induction motors

Abstract

This article discusses the most important issues regarding the implementation of digital algorithms for control and drive technology in industrial machines, especially in open mining machines. The article presents the results of tests in which the algorithm and drive control parameter settings were not selected appropriately for voltage-fed induction motors, and where the control speed was not verified by any of the available motoring or simulation methods. We then show how the results can be improved using field-oriented control algorithms and deep parameters analysis for sensorless field-oriented performance.
