Abstract

We model the longitudinal dynamics of a VSTOL aircraft as a nonlinear hybrid system with three modes corresponding to typical aircraft behavior. Due to the nonminimum phase property of the aircraft, exact feedback linearization will not stabilize the aircraft. Using dynamic extension, approximate feedback linearization provides a stabilizing control in each mode. We show that the system will track with bounded error in each mode as well as across mode switches. Two examples of common VSTOL manoeuvres demonstrate the effectiveness of the switched control scheme
