Abstract
This article presents the development of an algorithm for speed control of the induction motor by means of the DSP core microcontroller TMS320F28069M, which is in charge of performing the digital treatment of the voltage and current signals measured to estimate the speed of rotor and close the control loop. The algorithms consider the operating limits and the characteristics of the DSP, together with an interface that allows monitoring the estimated speed, and modifying the operating point and the constants of the PI controller, the controller output is assigned to an output of the DSP PWM_DAC which is connected to an ABB ACS800-U1 frequency converter in remote mode to carry out the motor speed change by means of a V / F control law.
