Abstract

The INO340 stands for Iranian National Observatory, which is an Alt-Az reflecting optical telescope with 3.4m main mirror diameter. At the moment, the conceptual design of telescope control system (TCS) has been finished and the detailed design is developing. Distributed control system configuration has been selected for the architecture of TCS design. TCS is responsible for the control of the telescope structure with its mirrors including 3 major subsystems: TCSS, MCS and AOS. All subsystems of TCS are designed with an adequate safety subsystem. This paper presents the TCS architecture of INOCS, and then it focuses on the requirements and the major functionalities of MCS. We provide different analysis of MCS using related parameters such as wind effect, encoder resolution and etc. Based on the simulation results the optimum sets of parameters and functions of different modules are concluded. The Alt balancing and mirror cover sub-systems are also briefly presented. Finally, we present the evaluation results of MCS design based on the pre-defined telescope requirements.
