摘要
巨型化的发展趋势使得望远镜驱动系统要承受更强的非线性干扰,从而对机架驱动伺服系统的设计和调试提出了严峻的挑战。介绍了极大望远镜的机架驱动系统的组成结构和驱动方式;分析了控制系统中存在的主要非线性干扰以及这些干扰对位置伺服系统跟踪精度的影响;总结了当前在望远镜的机架驱动控制系统中采用的和正在尝试采用的几种控制策略,并分析了每种控制策略的适用范围和不足之处。
Astronomical telescopes become more and more huge, which lead its driving system to bear heavier nonlinear disturbances, and the price of being more huge is an extraordinary technical challenge to its control system.The configuration and driving modes of giant telescopes mount driving system were Introduced. Nonlinear disturbances which exist in mount drive system and how these disturbances worsen the tracking precision of position sevo system were analysed. Most of the contol methods used in giant telescopes mount control system were summarized one by one. The disadvantages for every control method were also analysed.
