Research on Electromagnetic Launch Control System Based on ARM and FPGA Architecture

Aiming at the high reliability design problem of electromagnetic launch control system, this paper proposes a control system design method based on ARM and FPGA architecture. The overall structure of the control system is divided into three parts: box control, subsystem control and module control. Among them, the subsystem controller is composed of a control motherboard and a pulse power management board. The control motherboard is designed based on the architecture of ARM and FPGA. ARM runs logic related processing, and FPGA processes timing control, synchronous feedback and other functions that require high time accuracy. Based on the host computer software, the current curves of specific discharge energy and discharge time sequence are analyzed. The verification results show that the discharge current waveform can be controlled by controlling the discharge sequence of Pulse Forming Network (PFN) through the control system. Under the condition of long equal interval discharge sequence, the peak current decreases and the wave pattern changes gently. The electromagnetic launch control system realized in this paper has high scalability, can monitor more than twenty pulse power units, and can achieve highly reliable control of the launch system based on single shot and continuous shot operation mode.
