Application of Improved Genetic Algorithm PID Foreign Body Removal In Laser Power Grid

Because of its excellent characteristics, the laser has been applied to the field of foreign body removal in the power grid, and has great potential for development. To remove the foreign bodies efficiently, the control system of the laser’s two- dimensional turntable should be studied. By combining the improved genetic algorithm with PID control, the selection of mutation probability and crossover probability is improved. The results of MATLAB simulation show that the improved genetic algorithm PID zero overshoot, short time lag, and fast response speed when the unit step signal and interference signal are input simultaneously PID, compared with the traditional genetic algorithm PID and the traditional PID, the anti-jamming property is stronger and the system robustness is better. From the optimization curve of an objective function, it can be seen that the convergence speed PID of the improved genetic algorithm is much faster than that of the traditional genetic algorithm PID.
