Abstract

An adaptive tracking control scheme for the conversion mode of twin tilt-rotor aircraft is proposed under input saturation and fixed-time prescribed performance requirements. First, due to the tilting features, a longitudinal switched nonlinear model is constructed in view of aerodynamic analysis to facilitate controller design. Second, considering the input saturation, the distribution-based multi-auxiliary systems are designed to match the requirements of time-related flexible prescribed performance. Third, a novel adaptive switching controller is designed to reduce the influences caused by modeling uncertainty. Finally, an XV-15-based simulation result verifies the effectiveness of the proposed method.

基于混合辅助系统的倾转旋翼机转换模式切换自适应跟踪控制

针对双倾转旋翼飞机在输入饱和和固定时间规定性能要求下的转换模式，提出了一种自适应跟踪控制方案。首先，针对飞机倾斜的特点，从气动分析的角度出发，建立了纵向切换非线性模型，便于控制器设计。其次，考虑输入饱和，设计了基于分布的多辅助系统，以满足与时间相关的柔性规定性能要求。第三，设计了一种新的自适应切换控制器，以减小建模不确定性对系统的影响。最后，基于xv -15的仿真结果验证了该方法的有效性。
