摘　　要：针对目前脉冲电源窄脉冲电流幅值难以检测的问题,以16位DSP芯片为控制核心,采用新颖的脉冲电流幅值检测方法,实现了对大功率脉冲电源主电路的控制功能;建立了电源系统的近似数学模型,利用模糊推理在线整定PID控制器的3个参数KP,KI,KD,实现对脉冲电流幅值的闭环控制。利用Matlab对电源系统进行了仿真,结果证明模糊PID控制器具有较高的控制精度和较好的稳定性。In view of the problem that the peak of the narrow pulse current is difficult to detect,the paper presents the pulse power control system based on DSP including hardware, and uses a new method of pulse peak detection.Meanwhile, the system adopts fuzzy-PID algorithm,because the controlled deceive is nonlinear and uncertain.According to fuzzy infer- ence,the parameters Kp,Kt,KD of PID are corrected on-line.After founding approximate math model, the simulative results by Matlab and the operating report verify that the control system is accuracy and steady.
