Research on large aperture telescope drive control technology

摘要

The direct drive motor of large aperture telescope, integrated with the telescope mechanic structure, has characteristics ofhigh load torque and large moment of inertia. The control method of drive system should be specially designed for theheavy load. This article aims to list the key issues of engineering technology applied to large aperture telescope. Drivecontrol architecture and method, as well as design requirements of segmented direct drive motor on large astronomictelescope, are discussed in this article.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
