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。
The generalized predictive control (GPC) method is used to design a flight controller with low-altitude terrain tracking. The system dynamic model is used to predict the future output of the system. The performance index of predictive tracking error and future linear control combination is proposed. By minimizing the performance index, Generate optimal control input. In order to enhance the stability of the control system, the controlled object is augmented according to the linear feedback principle. The results show that the controller has accurate tracking performance.
