Abstract

In this paper a new variable structure control law for uncertain MIMO systems is investigated. The conditions for the existence of a sliding mode is derived. The asymptotic stability of the VSS is studied by using the Lyapunov V-function method. By using these conditions we have successfully designed a longitudinal position and tracking variable structure control system for the F-18 aircraft MIMO model with parameter perturbations. The longitudinal dynamics of F-18 aircraft with parameter perturbations is considered. Finally, simulation results for VSS both with chattering and free of chattering cases are presented to show the effectiveness of the design methods
