On Design And Engineering Realization Of The Cable-Cabin Structural Control Hardware For Large Radio Telescope

This subject stems from CAS Knowledge Innovation Project item: Optomechatronics Simulation and Experiment in the Cable-Cabin Support and Point-Track System for Large Radio Telescope. The 500-metre Caliber Spherical Radio Telescope is the largest one built and to be built. Its capability is one quantity grade higher than the others' available. Aiming at the shortcomings of the existing telescope, our scientists put forward a new Optomechatronics project. To validate the feasibility of the project, we built 50-metre model.From the engineering practice of the Optomechatronics Design for FAST, the working principle for system and hardware realization are described, and motor ascending and descending velocity arithmetic is discussed in this thesis, including the realization of the system control loop, the principle of servo control card and its hardware and software realization, the principle of moment real time detect equipment and its hardware and software realization. Aiming at the fact that motor trends to dither when its velocity changes abruptly, this thesis put forward the motor ascending and descending velocity arithmetic. I wish the thesis's work can provide reference for the building of 500-metre radio telescope.
