Abstract

Magneto-electric encoders have been widely used in industry and military applications because of their good shock resistance,small volume, and convenient data processing. However, the characteristics of a magneto-electric encoder’s signal generator and hallsensor changes minimally with temperature variation. These changes cause an angle drift. The main purpose of this study is toconstruct the compensation system of a neural network and constantly update weight coefficients of temperature correction by finiteiteration calculation so that the angle value modified can approach the angle value at the target temperature. This approach is used inadaptive correction of the angle value.
