英文摘要：

Theoretical analysis on the linearity of rotating displacement sensor, the magnetic induction density of radial magnetic field is the key facter that affects the linearity of rotating displacement sensor,while the magnetic induction density is affected by such factors as the length and radius of the primary coil and prejudicial distance and radius of Prejudicial disc and primary exciting current. After optimizing calculation of the linearity of rotating displacement sensor, the parameters has been optimally determined. Several analogue test of electronic regulator system are made on the basis of analogue test of electronic system, such as internal link system and external link system. The optimal parameter has been calculated on the well-balanced state of rotating displacement sensor, and it was very good in the aspect of both dynamic state that is 0. 25 s and linearity is 0. 4% in the electronic regulator system. It can meet the needs of well-balanced state of diesel.
