Implementation of Brushless DC Motor Speed Control with Proportional Integral Derivative Control Using Ziegler-Nichols Open-Loop Method

Brushless DC motors have problems with speed, whereas Brushless DC motors have pretty high speeds, and control is needed to reach a certain speed. The control proposed in this study is Proportional Integral Derivative (PID) with empirical parameter tuning, making it easier to implement. The method used in PID control uses the Ziegler-Nichols (ZN) open-loop method; in this method, the initial stage of the motor is run without control to obtain an open loop curve, and then from the graph, the PID parameters are obtained with the ZN Open-Loop table rules. Then, after obtaining PID parameters such as Kp, Ki, and Kd, they will be entered into the programmed digital PID control, and the control will be tested with three test schemes. The results obtained from the tests that have been carried out, namely the response of Brushless DC motor speed control by implementing the ZN open-loop PID tuning method, namely the control can explore a fixed setpoint at a speed of 2250 RPM and a changing setpoint, with a rise time and settling time below 3 seconds and has a steady state error below 5% when the motor is loaded.
