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。In order to meet special requirements of the high pulsed power supply for the ETC load and to make up the shortages of the existing controllers,FPGA was used to design a kind of Nios II embedded control system so as to effectively regulate the current waveform of the pulse power.A type of IP core of high performance controller described by means of VHDL language was presented,and it was accomplished with the help of the top-down modularized method,as well as the simulation and the verification of the IP core were carried out.This control system can generate multichannel and variable signals to trigger the next executive circuit,the signal can be adjusted at nanosecond.This system can also improve the quality and scalability,anti-interference ability and control precision.Simulation results showed that the system can greatly improve the accuracy,meet the requirements under the condition of strong electromagnetic interference.This system can simplify the hardware structure by use of instrument technology,and guarantee the real time capability of the control system,it can also provide a new kind of method for the measurement and control of compensated pulsing alternator.
