Abstract：A two-phase four-pole air-core compulsator is designed and its basic electromagnetic characteristics are analyzed. The absence of specific compensation components simplifies the compulsator structure design and increases the reliability and pulse current versatility. Considering the current coupling, the rotor speed change and the variable load resistance characteristics, the mathematical model of the discharge process for driving electromagnetic guns is established. The accuracy of the mathematical model is verified by the co-simulation result of finite element softwares Simplorer and Maxwell. Taking the projectile acceleration ratio as objective function, the differential evolution algorithm is used to optimize the firing angle and the value of series inductor; thereby the optimal pulse waveform is obtained. The combination of mathematical model and intelligent optimization algorithm provides an effective way for the optimization of waveform adjustment.
