【Abstract】 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.更多还原
