For a single moving-mass controlled reentry vehicle, the aim of control is tracking and stabilization in roll and yaw channel, respectively. Firstly, the model of reentry vehicle is established with Coriolis Theory, and nonlinear model for design is derived. Then, grey prediction based on GM(1,1) is presented to predict the error between the rolling angle and command. And grey prediction PID controller is designed with function based on grey prediction. At last, simulation and comparison are carried out; the results show the system has better response, better adaptability and stronger robustness than traditional PID controller.
