Control of FAST Feed Fine-Tuning Test Platform

摘要

To locate the feed support system accurately is one of the key technologies for constructing the FAST- a five-hundred-meters aperture spherical telescope. The control technology of the feed support system is studied in this paper, and a new test platform with two layers of Stewart platform is built for the experiment of the control system. Some key technologies such as the prediction and interpolation are discussed in detail. Finally, the control system is applied on the platform successfully and the experiment results show the efficiency of the system.
