Abstract

The article describes the development of an automated control system for electric drives, which includes a doubly fed induction motor, a digital position sensor and National Instruments equipment, represented by the PXI modular platform and LabVIEW software. The features of the interaction of software and hardware of the electric drive control system are considered. During operation, the system uses various levels of interaction of virtual instruments within one project. Thus, the use of virtual instruments of the project occurs at the level of the personal computer of the workplace, controller and the module with a programmable logic integrated circuit. The method of using a dynamically connected library for the calculation of parameters and state variables of the electric drive in real time is presented.
