Abstract
In order to improve the firing density and damage efficiency of the electromagnetic gun, the control algorithm of multiple rounds simultaneous impact(MRSI) of the electromagnetic gun was established by controlling the initial velocity of projectile and the time interval of the projectile launch. Under the premise that the electromagnetic gun can effectively improve the strike density and damage efficiency, the allowable distance error and the allowable flight time error are set, the fourth-order Runge Kutta method is used to calculate the outer ballistic. According to Pareto genetic algorithm, the objective function, namely two allowable errors, is optimized to obtain the optimal solution of muzzle velocity and angle of multiple projectiles. The simulation verifies that the electromagnetic gun can achieve multiple rounds simultaneous impact in different ranges, and verifies the feasibility of the algorithm to achieve multiple rounds simultaneous impact, which is of great significance to improve the damage efficiency and fire density of the electromagnetic gun in the future.
