摘      要：This paper investigates a switching control strategy for the altitude motion of a morphing aircraft with variable sweep wings based on *** morphing process is regarded as a function of the system states and a related altitude motion model is ***,the designed controller is divided into the outer part and inner part,where the outer part is devised by a combination of the back-stepping method and command filter technique so that the’explosion of complexity’problem is ***,the integrator structure of the altitude motion model is exploited to simplify the back-stepping design,and disturbance observers inspired from the idea of extended state observer are devised to obtain estimations of the system *** control input switches from the outer part to the inner part when the altitude tracking error converges to a small value and linear approximation of the altitude motion model is *** inner part is generated by the Q-learning algorithm which learns the optimal command in the presence of unknown system matrices and *** is proved rigorously that all signals of the closed-loop system stay bounded by the developed control method and controller switching occurs only ***,comparative simulations are conducted to validate improved control performance of the proposed scheme.
