摘要
运用广义预测控制（ＧＰＣ）方法，设计了低空地形跟踪的飞行控制器；利用系统的动态模型预测系统未来的输出，提出了预测跟踪误差和未来控制线性组合的性能指标，通过使性能指标最小，产生最优控制输入。为了增强控制系统的稳定性，根据线性反馈原理对被控对象进行了增广。结果表明，该控制器具有精确的跟踪性能。
A generalized predictive control method was used in this paper for design of cruise missile terrain following controller. A performance index which combinated predictive tracking error and future control is presented,then optimal control input is generated to minimize the performance index.The system is augmented to enhence stability.The result shows that the controller exhibits robustness and excellent tracking performance.
