Space radiation effect on fibre optical gyroscope control circuit and compensation algorithm

【摘要】 The process of a γ-irradiation experiment of fibre optical gyroscope(FOG) control circuit was described,in which it is demonstrated that the FOG control circuit,except for D/A converter,could endure the dose of 10krad with the protection of cabin material.The distortion and drift in D/A converter due to radiation,which affect the performance of FOG seriously,was indicated based on the elemental analysis.Finally,a compensation network based on adaptive neuro-fuzzy inference system is proposed and its function is verified by simulation.更多还原
