Optimization of Electromagnetic Railgun and Projectile’s Trajectory by Genetic Algorithm

In this paper, the optimization of the electromagnetic railgun and its projectile path is proposed. The circuit model is used to optimize and simulate the elec- tromagnetic railgun, in which the equivalent circuit of the railgun is extracted. Then the differential equations expressing the physics governing the system are obtained. Using the projectile path equations and simulate them in MATLAB, the output of the simulation of the electromagnetic railgun and its projectile path in MATLAB software has been analyzed. The main advantage of the mod- els used is that they can be used in matters of sensitivity and optimization due to their high speed. Based on the obtained outputs of electromagnetic railgun and projectile path, the cost function is presented, and then the effective pa- rameters of models are optimized using the genetic algorithm. The results show that the losses and costs are drastically reduced for the same purposes, and the waste of costs and energy is prevented.
