Designing high-performance controllers that do not saturate remains a challenge that cannot be addressed by linear control theory alone. This paper presents a control design methodology by which increasingly aggressive gains are used as the system converges to equilibrium. Stability of the resulting nonlinear control law is proved via the construction of a corresponding Lyapunov function. Performance and practicality is demonstrated by using the method to design a lateral-directional controller for the F18 HARV, using simulations models provided by NASA Dryden Flight Research Center.
