基于非线性模型预测的绳系系统系绳摆振控制

On the stability control of the rope system, a stability control method of tether swing for tethered system consisting of tether and tethered satellites during deorbitting is proposed in this paper. In this paper, a model of motion including satellite attitude motion is eatablished, and the dynamic equation of deorbit tethered system and the simplified equation that is convenient for controller design are proposed. According to the model prediction theory, the reference trajectory is designed by the optimization method, and then the stable tether swing nonlinear model predictive control method is designed based on the model predictive control method in this paper. Then, the feasibility of the designed controller and the reference trajectory are verified by the simulation of MATLAB software platform.
