针对一类刚体飞行器的姿态机动问题,提出了一种将飞行器姿态驱动到设定姿态的模型预测控制算法。通过构造合适的控制性能指标函数,对经反馈线性化处理的飞行器姿态运动方程设计了模型预测控制器。由于预测控制的一个重要特征是能实现对设定参考点或参考轨迹的有效跟踪,因此将要解决的飞行器姿态机动问题转化为对设定姿态的跟踪问题。仿真结果表明,所提出的模型预测控制算法成功实现了飞行器的姿态机动。
A model predictive control algorithm was proposed in this paper for a class of rigid aircraft attitude maneuver problem, which can drive the spacecraft attitude to a set point. A model predictive controller was designed by constructing a proper control performance index function to the aircraft attitude equations. One of the most important features of predictive control is tracking reference points or trajecto-ries, so aircraft attitude maneuver problem was transformed into an attitude tracking problem in this paper. Simulation results show that the proposed model predictive control algorithm has achieved aircraft attitude maneuver successfully.
