The development of industrial automation technology is increasingly sophisticated, directly proportional to the increasing production needs. The use of 3 phase induction motor technology as the main driving component of industrial machines is increasing. High reliability, minimum maintenance, and low price, the 3-phase induction motor is the most appropriate choice for use in industry. The 3-phase induction motor has drawbacks, one of which is not being able to maintain speed when there is a change in load. A closed circuit system using a programmable logic controller (PLC) and Variable speed drive (VSD) is a solution to maintain a stable motor speed. However, it still has the responsibility to reach the reference speed long enough. Some industrial machine productions require a stable 3-phase induction motor rotation speed. In this study, we provide a solution by using PID Autotuning control to accelerate the responsiveness and maintain the motor speed to the reference speed position when there is a change in loading. The test results using the PID Control method, the speed response, when there is a change in loading, is 2 seconds faster than without using PID control. With a speed error of 44.53 rpm or 2.9% of the 1500 rpm reference speed. Smaller than without PID with an error of 118.56 rpm or 7.9% of the 1500 rpm reference speed. © 2021 IEEE.
