Abstract
AbstractIn view of the constraints of amplitude and bandwidth of state and input variables in nonlinear system, a design method of incremental backstepping attitude control law with constraints is proposed. The characteristic of the control law is that incremental backstepping can solve the influence of modeling error to a certain extent, and then the update law with constraints can guarantee the Lyapunov stability of the system when there are constraints on the angular velocity and rudder surface of the aircraft. The simulation results of F-16 aircraft attitude control law show that the method has a good control effect when the aerodynamic derivative of the model is not accurate, and the method with constraints can ensure the stability of the system better than the conventional method when there are constraints on the rudder surface.KeywordsNonlinear systemControl with constraintsBacksteppingFlight control law
