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.
