    摘要:

    为发展一种集成旋翼控制的直升机高带宽飞行控制设计方法，基于显模型跟踪控制技术，在反馈控制模块引入旋翼运动信息并采用旋翼/机体控制增益的最优化设计提升直升机动稳定性，采用旋翼前馈增强控制提升直升机操纵频率，提出基于有效跟踪的显模型参数设计方法提升直升机小幅高频和中等幅度姿态控制的操纵品质。最后，基于高阶飞行动力学模型分析直升机操纵品质，结果表明：将旋翼控制用于直升机飞行控制设计能够在保持系统稳定性的同时提升操纵频率，直升机纵、横向操纵响应带宽分别提升18%和10%，纵、横向姿态快捷性分别提升25%和20%。

    Abstract:

    This paper presents a high-bandwidth flight control design for helicopters using an integrated rotor control system. Based on an explicit model-following control design, a rotor state feedback control law was developed and integrated into the baseline control system. The rotor/body feedback gains were comprehensively optimized to improve the stability of helicopter and a rotor control augmentation was designed to enhance command tracking ability, based on which a design method of command model parameters was proposed to improve helicopter attitude response bandwidth and attitude quickness. Finally, by a high-order helicopter flight dynamics model, the helicopter handling qualities were analyzed. The results show that the integrated rotor control system can maintain the stability margin of the baseline control system while improving the control frequencies. The roll and pitch control bandwidths are improved by 10% and 18% respectively, while the roll and pitch attitude quickness are improved by 20% and 25% respectively.
