Design of high-precision two-dimensional calibration platform control system for detector array
摘要
Abstract
In order to realize fast and high-precision calibration of detector array,the control system of high-precision two-dimensional calibration platform for detector array is studied,and a closed-loop displacement control system using a single chip computer to control stepping motor and encoder is designed in this work.Firstly,the calibration principle of the platform and the design of hardware and software control system are introduced,then the control PID algorithm is studied.Finally,a calibration system is built to test the designed control system comprehensively.The experimental results show that the control system has good control ability.The positioning accuracy of the platform can reach-11～12 μm within the effective itinerary of 600 mm×600 mm.The variation coefficient of ten single point test data is 0.13%,and the average measurement error in continuous mode is 1.65%,indicating that the designed platform meets the calibration requirements of detector array and provides an effective means for the calibration of detector array.关键词
