【摘要】：针对高功率脉冲电源对电热化学炮负载的特殊需求以及现有控制器的不足,设计了一种基于现场可编程门阵列(FPGA)的Nios II嵌入式控制系统,从而有效调节脉冲电源的放电波形。采用自顶向下的模块化设计方法,通过VHDL语言设计了一种高性能控制器的IP核,并进行仿真验证。该控制系统能产生多路可调的脉冲触发信号,能较好地控制执行设备,其时序差可进行纳秒级调整,同时系统提升了可裁剪性、抗干扰能力和控制精度。仿真试验结果表明,系统工作可靠,精度得到提高,能够较好地满足系统在强电磁干扰下的运行要求。运用仪器仪表技术,简化了系统硬件组构,保证了系统控制的实时性,也为补偿脉冲发电机的测控提供了一种新方法。
[Abstract]:Aiming at the special demand of high power pulse power supply for the load of electrothermal chemical gun and the deficiency of the existing controller, a Nios II embedded control system based on FPGA (Field Programmable Gate Array) is designed to adjust the discharge waveform of the pulse power supply effectively. A high performance controller IP core is designed by using the top-down modular design method and VHDL language, and the simulation is carried out. The control system can produce multi-channel adjustable pulse trigger signal, can better control the execution equipment, and its timing difference can be adjusted in nanosecond order. At the same time, the system improves the trimming ability, anti-interference ability and control precision. The simulation results show that the system works reliably and the precision is improved, which can meet the requirements of the system under the strong electromagnetic interference (EMI). The application of instrument technology simplifies the hardware fabric of the system, ensures the real-time control of the system, and provides a new method for the measurement and control of compensated pulse generator.
