Design of a control system card for frequency inverter in FPGA

Abstract

Nowadays much energy has been allocated to what is being called the Internet of Things (IOT) but little attention has been devoted to the infrastructure aspects to support this designed model, particularly for industries wishing to embark on the IOT era. This work describes the design and implementation of scalar control software for induction motors based in FPGA technology, with emphasis on control features based on PWM and Space Vector Modulation techniques as a proof of concept project. From the perspective of the scientific methodology, the present work is classified as an applied research (regarding the nature of the study), quantitative (regarding the approach to the problem) and explanatory (regarding the objectives). As for the technical procedures to carry out the work, the case study was used from the context of the company that produces frequency inverters where the project is being executed. To achieve the main objective was instantiated a “soft processor” in FPGA and specified and implemented scalar control algorithms (and helper functions) that allowed validating the hardware implementation. In addition, were performed a set of tests on pilot hardware and an evaluation of results is presented.
