Přímé řízení momentu asynchronního motoru s využitím Depenbrockovy metody

Abstract

This thesis deals with the issue of one of the modern ways of driving AC machines, direct torque control. The work theoretically analyses this way of controlling induction engines, including a more detailed description of usable methods, then compares direct torque control with vector control, its advantages and disadvantages. The design and functional description of the control algorithm in C language for the Depenbrock method of direct torque control and implementation of this algorithm into the control system with a digital signal processor type TMS320F28335 is then performed. Last but not least, the user interface, created in LabView, designed to control this control algorithm and the entire drive, respectively, is designed and described. At the end of the work, the functionality of both the algorithm and the user interface is verified using laboratory measurements on the actual induction engine. The main part of this measurement is the verification of the functionality of the control algorithm and the user interface at various engine running conditions.
