【摘要】 研究了空天飞行器的再入制导预测律的设计问题。根据飞行器再入飞行所受的约束条件确定再入参考轨迹,设计非线性预测控制控制律使得飞行器跟踪参考轨迹,通过在性能指标中加入末端项,以及基于末端项设计局部非线性控制律来保证非线性预测控制律的稳定性。最后给出的仿真实例表明了本文所设计的控制律具有较好的跟踪性能。更多还原

【Abstract】 In this paper,the design of the aerospace vehicle’s re-entry predictive/tracking law is considered,the reference trajectory of RLV is decided by the constraints,and tracked under the nonlinear predictive control law.The stability is guaranteed by adding a terminal-state penalty in the cost function and using a local terminal-state controller which is based on the terminal cost function.Results of the simulation indicate the acceptable performance of the designed law to track the reference trajectory.更多还原
