Analysis of signal-obtaining error factor of sensor in gyro

The digital signal-obtaining for gyroscope is given. The single optic-fiber sensor via modulating intensity of light is used as measuring component. The influence on static transmission properties resulting from the special working environment (e.g. cryogenic and vacuum), the measure error because of the reflector shape of rotor, the abnormity of facula from sensor caused by the existence of engraving error, and the fixing error of sensor and the error of machine tool’s initial lignment are investigated. The mathematic model in every condition is founded, the simulation and relative experiments are done and the outcome is analyzed. The mathematic model and method of compensating technology are studied and some relative experiments are made. The result of study is useful to improvement of the signal-obtaining system. LIU Jian-feng was born in 1980. He is a Doctor of Guide, Navigation and Control in Harbin Engineering University. He received his B. Sc. in Machine and Automation in Harbin Engineering University in 2001 and M. Sc in Guide, Navigation and Control in 2003. He has long been pursuing the research of Signal Obtaining for Gyroscope. He developed the Wavelet in Gyroscope. His Doctor Thesis is The Research of the Wavelet in signal reading-out of Gyroscope YUAN Gan-nan is a Professor of Combination Navigation in Harbin Engineering University. He received his B. Sc. in the department of Automation Control in Harbin Military Engineering College in 1968. He has long been pursuing the research of the theory Combination Navigation. He developed the Combination Navigation (H/H ZD - 001A and H/H ZD - 001B), which filled the blank of this field of our country. During the year 1989–1998, he has been awarded the various honors many times. The Combination Navigation System has been equipped in m many sorts of warships, exporting to the three countries of South Asia, making prominent contributions to the navy of our country. He has published many documents in our country and overseas. He was honored to be one of the leaders of this field. ZHAO Shi-jun is a Professor of Automatic Control in Harbin Engineering University. He received his B. Sc. in Automation Control in Ji Lin University in 1966. He has long been pursuing the research of the system of the control for missile. He taked part in the research of air to ship missile. During the year 1980–1999, he has been awarded the various honors many times. The System of control for missile has been useed in m many sorts of missile, making prominent contributions to the defence of our country. He has published many documents in our country and overseas. He was honored to be one of the leaders of this field.
