Abstract
A model of the antenna control system for the azimuth and elevation axes of the DSS 13 antenna is developed. This medel is used for simulation of elevation and azimuth dynamics, cross-coupled dynamics, and radio-frequency pointing error due to both input commands and wind disturbances. This model also serves as a tool for the antenna controller design. A modal state-space model] of the antenna structure was obtained from its finite-element model with a free-rotating tipping structure and alidade. Model reduction techniques applied separately for the antenna structure, elevation and azimuth drives, and rate-loop model reduce the system order to onethird of that of the original, while preserving its significant dynamic properties. Extensive simulation results illustrate properties of the model.
