一类非线性奇异摄动系统的轨道机动控制

摘要

In view of a class of nonlinear singular perturbed system which can be typically evolved into two time scales, a Composed control law for trajectory maneuver is researched by applying feedback linearization, in two step, to inner loop and outer loop. The trajectory maneuver control system of a certain UAV is simulated and the results show that the closed loop has good output tracking properties and parametric robustness in spite of simultaneous longitudinal and lateral maneuvers.%对于一类具有典型双时标特性的非线性奇异摄动系统，应用反馈线性化理论分内环控制和外环控制两步进行了轨道机动的组合控制规律设计。以某型飞机为对象进行的轨道机动控制仿真结果表明，闭环系统对同时进行的纵向和侧向机动有良好的输出跟踪，对参数摄动具有较好的鲁棒性。
