英文摘要	in this paper, a semi-physical ground test technology is proposed to simulate the disturbance of flexible solar panels on sun-tracking unit. In order to improve the precision of the semi-physical test, several methods have been designed. Firstly, semi-physical test platform with ultra-high stiffness and automatically adapted to motion errors without additional force is designed to provide foundation. Secondly, solar wing dynamic model is established and discrete by Wilson 6 method to calculate torque by real-time system. Thirdly, angular acceleration estimation of sun-tracking unit is obtained by nonlinear tracking-differentiator. Finally, simulation and experiment results show that platform can provide disturbance simulation torque, the platform can test the performance of sun-tracking unit. © 2019 IEEE.
