Implementación de un algoritmo para el control de velocidad de un motor de inducción mediante TMS320F28069M.

Abstract

This book presents the development of an algorithm for the speed control for the induction motor by means of the TMS320F28069M microcontroller, which receives the variable speed from a taco-generator, which is filtered and normalized by a circuit of its own design and elaboration, where the acquired electrical magnitude will be transformed to its digital value to be manipulated by the elaborated programming logic. The algorithms are detected based on the operating limits of the scalar control technique, and the characteristics of the DSP, the control technique together with the optimization algorithm used will provide the modifications with the harmonic content optimization, based on the method of frequency variation adopting a multilevel converter, which receives the control signals from the GPIO of the device acting as the final control element of the raised loop. The adopted multilevel converter converts the voltage coming from the CD BUS to a quasi-sinusoidal AC voltage thanks to the steps outlined above, the power supply to the induction motor that intrinsically carries the scalar control technique. Finally, a PI controller developed for the system is implemented, where the response of the system is monitored with the help of an interface which helped to observe the behavior of the proposed prototype.
