Research on electromagnetic coupled Theory High-speed Multi-stage Cylinder Linear Launcher

According to actual structure of High-speed Multi-stage cylinder linear launcher (HSMCLL), based on electromagnetic field theory, the mathematical model of the launcher is deduced, which considers inter-stage coupling effect. The discharge control strategy of the launcher is proposed. The dynamic performance of the launcher is simulated, and the current of drive coil and speed of armature are presented. Experiment results contrast with simulation results, they are coincidence well. It verifies the validity of the model and provides a new way for the study and implementation of control strategy of this kind of machine.
