Research and simulation of amplitude error and quadrature error for inductosyn

Two-phase amplitude and quadrature error of inductosyn have a great impact on the detection accuracy, through researching amplitude and quadrature error of inductosyn,eliminate its effects, and improve accuracy of inductosyn. First, analysis the characteristics of these two errors and their impact on the measurement accuracy. Then, research a new method, in the two position of 0° and 90°, respectively detecte their sine and cosine winding voltage , achieve amplitude and quadrature error detection, and amend their by using the software . Finally,experiments show that this new detection and correction method of error could improve the accuracy of Inductosyn.
