摘　　要：针对变形翼飞行器提出了一种自适应滑模控制算法。对形变造成的模型不确定性,采用自适应补偿算法消除其对系统稳定性的影响。将外界的扰动分解成匹配项和不匹配项,设计积分滑模控制完全消除匹配项对系统的影响,同时使不匹配项满足鲁棒性能指标。通过李雅普诺夫稳定性证明自适应积分滑模控制能使跟踪误差一致渐近稳定。最后,在含有不确定项的变形翼飞行器模型上进行仿真,验证算法的可行性和有效性。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.
