Digital Detection and Control System for Ring Laser Gyro

摘要：

The detection and control system is an important part of ring laser gyro (RLG) to process the signals by electronics. To overcome shortcomings of the traditional analog circuits, this paper puts forward a set of digital detection and control system. Based on the DSP TMS320F2812 and the necessary analog interface including acquisition circuits and driving circuits for the specific physics parameters of RLG, the hardware structure is built up. Adopting the fuzzy PID algorithm and wrong state detection service, the software flow is given in detail. Experiments are carried out to test the performance of the system. The results show tht precision of power voltage, power current light intensity and gyro drift can reach 2.1×10-4, 1.5×10-6, 2.5×10-5 and 4.5×10-3 respectively, indicating that the digital system has better performance than analog circuits, which will do a lot of good to RLG application.
