Industrial processes from longer time utilized servo motors .consequently Controlling the position of Direct Current servo motor is the first aim of this paper, During operation, happen disturbance inaccuracy of position and velocity servo plant .consequently the best proportional - velocity (PV) controller and natural phenomenal, named Electro-search(ES) algorithm for servo plant is used in improve position tracking of servo plant .proportional -velocity (PV) is closed-loop system has two terms: one to the position error (Kp) and the other used to the derivative of actual position (Kv) of the plant. Electro-search (ES) algorithm based on the movement of electrons through the orbits around the nucleus of an atom .where natural of the electrons goes to orbits with high-rise energy level (better fitness value). This method depends on atomic structure and used physical laws such as the Rydberg formula and the Bohr model. The efficiency of the ( ES) algorithm compared with other famous optimization methods such as the water cycle algorithm(WCA).this tested achieve by using MATLAB/SIMULINK. Results of the simulation offer that (ES) algorithm high speed, high accuracy, and efficient in improving the characteristic of the step response.
