Performance Evaluation Brushless DC Motor System With Variable Loads

The use of brushless DC motors will increase with the transition of conventional vehicle motors to electric vehicles (Electric Vehicles). The purpose of this study is to produce control that can maintain and increase the stability of motor rotation at changing or non-linear loads. It then performs testing of the created model. The control method used is PID. The control that is suitable for use in cases like this is the PID (Proportional Integral Derivative) control system. The best Kp, Ki, and Kd values obtained based on trial and error, and the values obtained are Kp = 1.1, Ki = 0.2, and Kd = 0.8. The response to distractions gets better and the response to speed variations gets better. In addition, the speed of the simulation results can follow the change in the speed reference with a slight overshoot in each transition of the speed value. The resulting system responds with a settling time value of 0.0035 s and a large overshoot with a value of 1.9%.
