| 摘 要： | 电磁轨道发射的过程中，电枢在膛内高速运动时会受到电磁力、电枢初始正压力、摩擦力、空气阻力、烧蚀阻力等多种因素影响，电枢的出口速度呈现出在一定范围内波动的特征。为了提高电枢的出口速度精度，针对膛内电枢与轨道摩擦不均衡性和烧蚀程度不确定的特性，综合考虑脉冲成形网络的电路模型与电枢的动力学特征，建立了电枢在膛内的运动开环控制仿真模型。通过仿真，得出了脉冲电源模块触发时刻与电枢出口速度之间的关系，提出了电枢出口速度闭环控制模型，探究了电枢出口速度控制可行方案。结果表明：应用闭环控制算法，可实现对电枢出口速度的精确控制。

| Abstract: | During the launching of electromagnetic railgun, movement of the armature will be influenced by many factors, such as electromagnetic force, armature initial positive pressure, friction force, air resistance and electrical erosion resistance when the armature is moving in the bore. The muzzle velocity of the armature will fluctuate in a certain range. To improve the precision of the muzzle velocity of the armature, based on the character of the uncertainty of friction and ablation degree of armature and rail, this paper presents a simulation model for the open loop control of the armature in the bore, considering the dynamic characteristics of the circuit model and armature. The relationship between the discharge time interval and muzzle velocity of the armature is obtained by simulation, the armature velocity closed loop control model is put forward, and the feasible scheme of armature velocity control is explored. The simulation results show that the closed-loop control can improve the control precision of the muzzle velocity of the armature. |
