Abstract

The invention relates to a method for self-calibrating a zero position of a fine and coarse machine of a double-channel multi-polar rotary transformer, which is characterized by comprising the following steps of: measuring code values theta fine' and theta coarse' of fine and coarse channels of the double-channel rotary transformer at a calibrating time T; measuring code values of theta fine and theta coarse of the fine and coarse channels at any time t after the double-channel rotary transformer is calibrated; calculating code values of theta coarse'' and theta fine'' of the fine and coarse channels of the corrected double-channel rotary transformer; and calculating to obtain a current real angle according to theta real=f1(theta coarse'', theta fine'', p). The method disclosed by the invention is used for simultaneously correcting the two channels to find out the zero position of the certain channel without rotating the rotary transformer.

Description

technical field

[0001] The invention relates to a self-calibration method for the zero position of a dual-channel multi-pole rotary transformer fine-coarse machine, which belongs to the field of electronic technology. A method for zero position self-calibration of a fine-coarse machine of a channel multi-pole resolver. The method can be applied to various types of dual-channel multi-pole resolvers. Background technique

[0002] As a precision angle measuring component, the resolver is widely used in military industry, shipbuilding, aerospace, smelting, mining and other industries due to its excellent vibration resistance, shock resistance and adaptability to various harsh environments.

[0003] In order to improve the angle measurement accuracy of the resolver, a dual-channel multi-pole resolver is usually selected in engineering practice. This type of resolver is a concentric sleeve shaft structure, which consists of two sets of resolvers, the fine machine and the rough m...
