摘　　要：与传统飞机使用的被动侧杆相比,主动侧杆系统提高了飞行员的飞行状态感知能力,帮助飞行员快速应对突发事件。本文针对主动侧杆非线性系统的建模与控制问题,为主动侧杆的关键部件及主要存在的非线性因素建立了数学模型。然后设计了主动侧杆系统的控制方案,其中包括力感曲线模型与基于模糊鲁棒控制的位置伺服控制方法,以补偿系统受到的非线性因素影响。仿真结果表明,所设计的系统能够很好地控制侧杆位移和力反馈,并抑制机械非线性对于系统的干扰,验证了控制方法的有效性。本文所提出的建模与控制方法对于主动侧杆系统的未来研究具有一定的参考价值。Compared with the passive sidestick used by traditional aircraft,the active sidestick system improves the pilot's flight state perception ability and helps the pilot to quickly respond to emergencies.Aiming at the modeling and control of the nonlinear system of the active sidestick,this paper establishes a mathematical model for the key components of the active sidestick and the main nonlinear factors.Then the control scheme of the active sidestick system is designed,including the force sense curve model and the position servo control method based on fuzzy robust control to compensate for the influence of nonlinear factors on the system.The final simulation results show that the designed system can control the displacement and force feedback of the sidestick well,and suppress the interference of mechanical nonlinearity to the system,which verifies the effectiveness of the designed control method.
