Abstract

The direct drive motor of large aperture telescope, integrated with the telescope mechanic structure, has characteristics of high load torque and large moment of inertia. The control method of drive system should be specially designed for the heavy load. This article aims to list the key issues of engineering technology applied to large aperture telescope. Drive control architecture and method, as well as design requirements of segmented direct drive motor on large astronomic telescope, are discussed in this article.
