Controlling the position of Direct Current servo motor is the first aim of this paper, by Bacterial Foraging Algorithm (BFA), the best Proportional – Integral - Derivative (PID) controller parameters were obtained through Mat-Lab application, including the simulation and modeling of Direct Current servo motor, BFA controller and conventional PID Controller as benchmark to the performance of BFA. Proportional – Integral - Derivative controller is a closed loop system, the error made by the Direct Current motor was corrected and determine the correct position to the desired point were controlled By integrating the Proportional – Integral - Derivative controller. Kp, Ki and Kd parameters was tuned to the find best values, which make the Direct Current Motor reached quickly the accurate position without any mistake.
