摘　　要：为解决因仿真设备的屏幕凹凸不平而使其反射特性存在剧烈闪烁,从而影响其仿真试验的置信度,提出在入射光处加调光器。设计基于TMS320F2812芯片的调光器系统,给出系统软硬件设计。该系统在PID控制基础上,添加前向反馈控制环节,增加了系统的跟踪特性。依据理论推算和大量测试结果,确定系统参数,结果表明该系统能够满足实际要求。A design scheme putting a dimmer before the incident light is proposed to solve the intense flash existing in dis-play reflection due to the uneven display of the simulation device. The dimmer system based on TMS320F2812 chip was de-signed. The system hardware and software design process is given in this paper. The innovation is that adds a forward feedback control link based on the PID control,and increases the tracking characteristics of the system. According to theoretical calcula-tion and results of extensive testing,the system parameters has been confirmed. The results show that the system meets the ac-tual requirements.
