Genetic algorithm for tuning a PID controller in adjustment facility of brushless motor

PID-regulation of the rotational speed of a three-phase brushless DC motor in the adjustment facility is considered. The functional diagram of investigated facility is described. The genetic algorithm, the manual tuning method and the classic Cohen-Coon method are used to adjust the PID controller. The control results of the three-phase brushless DC motor with the help of the PID controller are represented. A comparative analysis of the control outcomes results in calculation of overshoot, settling and rise time, and integral time absolute error. The genetic algorithm provides the control of higher quality in comparison with other considered methods.
