Meanwhile, it makes it difficult to apply angle conversion system to practical goniometry curcuit. The paper makes improvement on the fast following-up conversion and proposes a high-precision dynamic goniometer system and a nonlinear high-speed following-up conversion mode based on inductosyn. It analyses the causes contributing to the error and deduces the expression bf the basic goniometry errors caused by output signal inaccuracy, and also puts forward the bounds on error of axis-to-angle converting.
