摘　　要：Addressing the issues of nonlinearity,control redundancy and coupling,and system uncertainties in the deceleration transition process from level flight to hover in short takeoff and vertical landing(STOVL)aircraft,this paper establishes a six-degree-of-freedom nonlinear mathematical model for the STOVL deceleration transition process.An augmented control method based on L_(1)adaptive control is proposed for the deceleration transition process:dynamic inversion(DI)method is used to design the fundamental control laws for the inner and the outer loops,while an L_(1)adaptive controller is employed as the augmented controller to enhance performance and robustness under system uncertainties.Simulation results validate that this method effectively suppresses system uncertainties and improves the transition control performance.
