摘　　要：针对变体飞机变体过程中的模型不确定性和机动过程中遇到的扰动等问题,提出一种基于自抗扰控制的变体飞机机动控制方法,用于消除模型不确定性和外界扰动的影响以及提高机动控制的快速性和准确性。建立变体飞机非线性运动模型并分析变体飞机变体过程对飞机影响机理;采用自抗扰控制技术设计角速度鲁棒控制律;在扰动影响下分析了自抗扰控制律的控制性能;在气动参数扰动下结合变体过程,选取上半滚倒转机动验证所设计控制律的性能。数值仿真结果表明,自抗扰控制器能够消除模型不确定性、外界扰动和不同通道间的强耦合作用,完成上半滚倒转机动的控制,具有较好的解耦效果和较强的抗扰动能力,并且通过变体可以有效地提高飞机的机动性能和操纵面的控制裕度。Aiming at the problems of model uncertainties caused by morphing aircraft during morphing process and disturbance encountered when maneuvering,a morphing aircraft maneuver control method based on active disturbance rejection control(ADRC)is proposed to eliminate the influences of model uncertainty and external disturbance and improve the rapidity and accuracy of maneuver control.Firstly,a nonlinear model for morphing aircraft is established and the impact mechanism of morphing process is analyzed.Then,the ADRC technique is used to design the angular rate robust control law and the control performance of ADRC law is analyzed under the influence of disturbance.Finally,the immelmann turn maneuver is selected to verify the performance of the designed control law with aerodynamic parameters perturbation combined with the morphing process.The simulation results show that the method possesses good decoupling effect and strong disturbance rejection ability.Moreover,the aircraft′s maneuverability and the control margin of control surface can be effectively improved through morphing.
