A small and high accuracy gyro stabilization Electro-Optical platform

摘要

A high accuracy line-of-sight ( LOS ) Stabilization system based on digital control technology was designed. The current feedback closed-loop system was introduced which uses the CCD graphic and resolver to constitute the position closed-loop and uses the optic fiber gyro to constitute the rate closed-loop. In order to realize zero steady-state error of angular output in counteracting disturbance from carrier, a PII~2 (proportional-integral-double integral) control scheme is proposed. The hardware configuration and software system is presented. Experimental results show that the system has perfect dynamic and static performance and the technical requirements were satisfied.
