Guibin Peng, Xinglong Chen, Guozhong Zhou · International Conference on Electric Information and Control Engineering · 2012
A new preamplifier of inductosyn is designed and simulated. The SPICE simulation results show that the new preamplifier could achieve a precise amplification for the output signal of inductosyn. In addition, the high order harmonic noise and common mode interference introduced by inductosyn can be suppressed effectively. Compared with the traditional preamplifier of inductosyn, the new preamplifier has a simpler structure and higher accuracy. So, it is very suitable for the angle measuring system based on inductosyn.
