A novel adaptive integral sliding mode tracking controller is proposed for a morphing aircraft.The adaptive compensation algorithm is used to dispel the effect of parametric uncertainty on system stability.The perturbation can be projected into the matched and unmatched spaces.The additional integral term in the sliding surface reduces the steady state error and also provides one more degree of freedomwhich minimizes the Hinfinity norm of unmatched perturbation.It is shown that the stability of the closedloop system can be guaranteed with the proposed adaptive sliding mode control strategy.The feasibility of designed control scheme is demonstrated by a morphing aircraft model application.
