The Relationship between Dynamic and Static Precision of Angle Sensor

The velocity or the angular velocity is difficult to be measured.At most time,the velocity is obtained by differentiating the displacement or integrating the acceleration with respect to time,except in individual situations the velocity value can be obtained by some linear function.The higher the position or angle sensor precision is,the higher accuracy velocity can be obtained,but in turn,may not be set up.Based on the characteristics of the Inductosyn,the relationship between the dynamic precision and the static precision is discussed,and extend the conclusions to other angle sensors.It is a good reference for the design of the velocity-sensitive system and the selection of the angle sensor.
