Abstract: A semiconductor Laser Diode (LD) temperature control system based on Ziegler-Nichols tuning PID was introduced. According to the requirement of temperature stability in the LD system, the parameter auto-tuning Ziegler-Nichols algorithm and analog circuit was adopted to carry on the control of temperature.

Abstract: A new design of using FPGA to realize array beacon light switching is preferred. Based on spatial diversity laser communication, the problem of multiplexing beacon light celerity and synchronism switching has been settled. Karnaugh map method was used in the paper to generate the time sequencing driving four motors, which was used in the schematic diagram design. Experiment results show that the system(or the design) in this paper cooperated with multiplexing beacon light has been realized, which simplifys the traditional beacon light switch system frame.
