Study On Software For The Control System Of Large Spherical Radio Telescope

Based on the in-depth understanding of background and requirements for the mechanical, electronic and optical design for the large radio telescope, software of control system for the 50 Meter Experiment Model is accomplished.The dissertation present an actualization of servo dictate derived from DDA. The distribute control system has been studied deeply. The digital communication design of the control system is introduced. The CAN bus design of this distribute control system is proposed. Software global scheme, systemic analysis, module partition and code realization of the out-loop control system is presented. Based on characteristics, nonlinear, structure time-variable, delay and control system modeling difficulty, parameter fuzzy self-turning fuzzy-PID algorithms and non-parameter modeling self-turning algorithms and each application in the 5 and 50 Meter Experiment Model is studied deeply.
