非线性解耦控制与飞机敏捷性机动

首先介绍了以微分几何控制理论为基础的非线性系统解耦理论，给出了解耦控制律的综合方法及解耦闭环系统平衡点的计算方法，并对解耦系统的稳定性进行分析，随后用非线性解耦理论研究了飞机非线性运动的三种解耦运动模式，并讨论了飞机非线性解耦控制规律的线性近似解，最后用飞机非线性运动的三种解耦运动模式实现了三种形式的敏捷性机动，结果是满意的。为飞机敏捷性，直接力控制和过失速机动问题提供了一种理论研究方法。

NONLINEAR DECOUPLING CONTROL AND AIRCRAFT AGILITY MANEUVERS

In this paper the decoupling control theory for nonlinear multivariablesystems based on Differential Geometry Control Theory is introduced.A synthesis procedureof the decoupling control law for the nonlinear system is given. The calculation of equilibriumpoints for the nonlinear decoupled system is discussed.The stability of the decoupled closed-loop nonlinear system is also studied.Three forms of decoupling controls for aircraft nonlinear motion are studied with thedecoupling control theory.For the engineering application linear approximation of the aircraftnonlinear decoupling control law is discussed.Finally,three forms of agility maneuvers arerealized by three nonlinear decoupling control forms of aircraft motion and the results aresatisfying.The study will provide a new theoretical approach to investigate aircraft agility,the direct force control and post-stall maneuver of modern combat aircraft.
