Implementación de un algoritmo de control mediante DSP para el motor de inducción.

Abstract

This book presents the development of an algorithm for speed control for the winding rotor induction motor by means of the microcontroller with DSP core TMS320F28069M, which is responsible for performing the digital treatment of the signals coming from the measurement circuits coupled to perform the closing of the proposed control loop, the signals are filtered and normalized by a circuit designed by Author, where the acquired electrical magnitude will be transformed to its digital value to be manipulated by the programming logic developed in order to meet the objective proposed. The algorithms were made based on the operating limits of the control technique used and the characteristics of the DSP, with which the motor speed will be estimated at a specified operating point which is compared to the set point speed specified in the PI controller, which performs the speed change depending on its proportional and integral constants with the help of an output of the PWM_DAC DSP which controls the final control element. The adopted frequency converter is in remote mode and receives the control signals from the PWM_DAC pin of the device, thus changing the motor speed. Providing the power supply to the induction motor that intrinsically leads to the raised control.Finally, the response of the system is monitored with an interface which helped to observe the behavior of the raised prototype.
