Study on improving method about testing accuracy of the UAV pitch angle rate

摘要：

When the UAV is in Short period movement,it needs to increase longitudinal damping for keeping longitudinal stability. For flying stability, longitudinal damping controls tail wing according to longitudinal angle rate variety.For this reason,testing accuracy of longitudinal angle rate and taking a value of feedback coefficient is very important. Longitudinal angle rate is measured by velocity top in UAV.For the flexibility transforming of the UAV machine body structure,it will be severity influence to test accuracy of the UAV pitch angle rate.So it is important to do research on how to let up the influence and find out the measure.There is a wave point in the belly of the UAV machine body structure,in which move variety rate is zero.Making assurance the point and installing the sensor can reduce the influence in testing accuracy of the UAV pitch angle rate. By increasing filter wave link and choosing reasonable parameter,it will filter wave and clear up invalid number to judge feedback coefficient scope.
