Research on zero bias characteristic of FBW gyro

摘要：

　　Zero bias is an important performance index of FBW gyroscope.Based on the given gyroscope experiments,we studied zero bias of random error properties,temperature characteristic,large overload environment variation,and then calculate FBW gyro bias,bias stability,zero bias repeatability.We use Kalman filter into FBW gyroscope for random error compensation.Through least-square method,we fit temperature scale factor and temperature bias of FBW gyro.The experimental results show that the compensation method has the advantages of simple operation,effectively compensation for measuring error of FBW gyroscope which is induced by temperature,and has strong engineering using value.
