Single moving-mass asymmetrical reentry vehicle modeling and control

Based on isolation method modeling, through analyzing the moving mass and the vehicle separately, a dynamic system model of single moving-mass asymmetrical reentry vehicle is studied. According to the model, the dynamic characteristic of the asymmetrical reentry vehicle is analyzed and the roll control scheme is put forward. By reasonablly simplifying the nonlinear model, the transfer function is derived and the controller parameters are devised using the algebraic method. The veracity of the model and the feasibility of the control scheme are validated by mathematical simulation. ©, 2015, Chinese Institute of Electronics. All right reserved.
