    Abstract

    In this paper, the performance of a control system for the azimuth axis of a two-meter telescope is investigated. The system, with a design based on the PID algorithm, achieves tracking accuracy requirements at low cost using two, low-resolution encoders, as shown via simulation. An encoder error model is developed and used in the simulation to study the effects of various encoder resolutions and accuracies
