Design And Research Of Integrated Data Processing And Servo Control System Of Telescope

Large optical telescope system is the main equipment to detect the spatial target,it is required that accurately and quickly, smoothly tracking of the target in the processof the space target detection and tracking process. Optical servo system is animportant part of the large optical telescope system; the telescope trackingperformance will be directly affected by the performance of the servo system. So inthis thesis, the optical telescope turntable servo control system is studied and aturntable servo controller and a kind of PC control software are designed.First, a brief analysis of the research status of telescope servo control system andthe development status of electrical control software is given and the researchsignificance is elaborated. The structure of the various components of the servocontrol system is described and the overall design scheme of the system is given.Secondly, according to the needs of the control system, a kind of PC controlsoftware is designed which is based on MFC, and object-oriented programmingmethod is used, the C++language is used as the programming. A detailed descriptionof the functional requirements of the control software and the implementation of thevarious functional modules is given.Again, a servo controller which is based on ARM and CPLD is designed. Thehardware structure of the servo controller is described, and the overall design scheme of the controller software is given. Under the guidance of the scheme, we completethe CPLD program and the ARM program and the controller design finally.Finally, a platform for Servo control experiments is builded. And the speed loopand position loop experiments were done with the control software which is designed.And the performance of the servo control system are analyzed, and tested a partialfunction of upper machine servo control software is tested.
