针对受多源扰动影响的四旋翼无人机的飞行控制问题,提出一种基于多源扰动补偿和分层滑模控制的自调节滑模控制算法。将四旋翼无人机系统分成一个2自由度双输入全驱动子系统和一个4自由度双输入欠驱动子系统,并在此基础上定义全驱动子系统的滑动变量。提出一种新型的分层滑模控制器滑动变量构造方法,并采用该方法设计欠驱动子系统的滑动变量。采用广义Super-Twisting干扰逼近器观测系统中的多源扰动,并设计模糊补偿器对干扰逼近器的逼近误差进行补偿。利用组合幂次趋近律设计趋近增益自调节滑模控制器,并使用带模糊补偿器的干扰逼近器抑制多源扰动的影响。分析所提控制算法各核心模块的作用,并将该控制算法与现有控制算法进行对比。对比结果表明,所提控制算法具有良好的多源扰动抑制能力,并且能够提供更优异的动态控制性能。

For the flight control of quadrotor unmanned aerial vehicles (UAVs) affected by multi-source disturbance,a self-tuning sliding mode flight control algorithm based on multi-source disturbance compensation and hierarchical sliding mode control is proposed.The quadrotor UAV system is divided into a two-degrees-of-freedom dual-input fully-actuated subsystem and a four-degrees-of-freedom dual-input underactuated subsystem,based on which the sliding variable of the fully-actuated subsystem is defined.A sliding variable construction method for hierarchical sliding mode controller is proposed,and the sliding variable of the underactuated subsystem is designed by adopting this method.A generalized Super-Twisting disturbance approximator is designed to observe the multi-source disturbance,and a fuzzy compensator is designed to compensate for the approximation error of the disturbance approximator.A reaching gain self-tuning sliding mode controller is designed by utilizing the combined power reaching law,and the disturbance approximator with fuzzy compensator is used to suppress the influence of the multi-source disturbance.The roles of the core modules in the proposed control algorithm are analyzed,and the proposed control algorithm is compared with the existing control algorithms.The comparison results show that the proposed control algorithm has good multi-source disturbance rejection ability,and can also provide superior dynamic control performance.
