非线性预测控制在巡航导弹地形跟踪中的应用

Application of Nonlinear Predictive Control in Cruise Missile Terrain Following

建立了巡航导弹的非线性动力学模型，针对该模型的非线性连续预测控制方法，提出了预测跟踪误差和跟踪误差率线性组合的性能指标，通过使性能指标最小，产生了巡航导弹地形跟踪的最优非线性反馈控制器。通过对虚拟地形的跟踪验证了控制器的性能，结果表明，该控制器不仅具有精确的跟踪性能而且具有良好的鲁棒性。

Nonlinear dynamic model of cruise missile is established,a nonlinear continuous predictive control method based on the model was studied in this paper.A performance index which combinated tracking error and yate of tracking error is presented,then,optimal nonlinear feedback control law is generated to minimize the performance index. Cruise missile terrain following controller is designed by using this method. Tracking performance of terrain following controller is tested by tracking an imaginative terrain. The result shows that the controller exhibits robustness and excellent tracking performance.
