Major Disadvantage

We present induction motor speed control using optimal PI controller fuzzy gain scheduling. To improve PI controller performance, we designed fuzzy PI controller gain tuning for indirect-field oriented IMspeed control using fuzzy rules on-line to adapt PI controller parameters based on error and its first time derivative. To overcome the major disadvantage of fuzzy logic control, i.e., the lack of design technique, we propose optimization of fuzzy logic tuning parameters using a genetic algorithm. Optimally designed fuzzy logic provides suitable PI controller gain to achieve the desired speed while varying load torque and parameters. Simulation demonstrated the performance of the proposed optimal fuzzy-logic tuning PI controller, and numerical validation results of our proposal showed performance comparable to a fuzzy controller having parameters chosen by a human operator.

Speed Change

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.
