An object attitude adaptive adjustment servo control device and method

Abstract

The invention discloses a servo control device and method for self-adaptive adjustment of object posture. The device includes a differential eddy current probe, an eddy current detector, and a posture adjustment servo system. Utilizing the high sensitivity of the differential eddy current signal, the differential eddy current signal is used as the self-adaptive object posture. Adjust the control signal of the servo control system, automatically adjust the relative attitude between the object and the surface of the metal reference object, realize the adaptive adjustment of the object attitude, and effectively solve the problem of automatic control of the relative attitude between the object and the metal reference object in the engineering application process .

Description

technical field

[0001] The invention relates to a device and method for automatically adjusting object posture, in particular to a servo control device and method for self-adaptive adjustment of object posture. Background technique

[0002] In engineering applications, it is often necessary to control the relative pose between an object and a reference object. For example, in order to ensure the best detection sensitivity during the eddy current testing process, the eddy current testing probe device should be relatively perpendicular to the testing surface, but for the eddy current testing of complex shapes, such as the eddy current testing of the inner wall of the center hole of the engine shaft, since the center hole of the engine shaft is the inner diameter For irregular holes that change, conventional manual inspection cannot ensure that the eddy current inspection probe device is always relatively perpendicular to the inner wall inspection surface, which has become an e...
