给出了非线性解耦系统平衡点的计算公式。用微分几何控制理论研究了飞机非线性运动的 3种解耦运动模式 ,并用这 3种模式实现了 3种形式的敏捷性机动和直接升力控制的 3种基本模式 ,即 An,α1和α2 模式。计算结果表明 ,给出的 3种解耦模式能精确地实现这些运动模式。

The calculation of equilibrium points for a nonlinear decoupled system is discussed.Three modes of decoupling controls for aircraft maneuvers are studied with the decoupling control theory based on the differential geometry control theory.Two types of agility maneuvers and three basic modes \%A\-n,α\-1 \%and\% α\-2\% of direct lift control are realized by the three nonlinear decoupling control modes.Simulation results show that the decoupling control modes can realize the direct lift control modes and the agility maneuvers thoroughly.The study provides a new theoretical approach to investigate aircraft agility and direct force control.
