Abstract
The array antenna test bed is a scaled model of the array antenna, designed and built to test antenna control system hardware, to test the development of control software, and to verify the control system algorithms. This article presents the development of the test-bed control system model of an array antenna and the analysis of its performance. It starts with the models of the mechanical hardware, which are combined into the rate-loop model and finally into the position-loop model. The control system algorithms consist of the command preprocessor, the position controller, the rate controller, and the backlash controller. The simulation results of the rate-loop model and the position-loop model show close coincidence with the test data. The analysis showed that the test-bed rate-loop bandwidth is 70 Hz and the position-loop bandwidth is 16 Hz, which exceed the expected system performance requirements.
