The space flexible solar wing is easy to be affected by the vibration from the satellite platform, which has characteristics of low frequency, dense frequencies and large static deformation. In order to ensure that the extension mechanism of the large flexible solar wing can realize the reliable, repetitive and stable deployment and retraction of the sun tracking, adynamic model of the flexible solar wing is established. On this basis, a double closed-loop control strategy of improved sliding mode and variable integral PID regulator is proposed to realize the double closed-loop control system of speed and current. Finally, the experimental system of peripheral circuit, driving circuit and position detection circuit based on single chip anti fuse FPGA is designed, and the experimental verification of large flexible solar wing deployment control based on FPGA is realized. Through the experimental verification, the system can achieve the vibration suppression function of the extension mechanism with high disturbance, and realize the engineering application that the large flexible solar wing can be repeatedly and smoothly unfolded and folded which has a certain application value and provides a reference for the subsequent engineering application.
