【摘要】 针对复合式高速无人直升机前飞速度控制中的操纵舵面冗余问题，以某型复合式高速无人直升机为研究对象，建立其纵向通道动力学模型。分析纵向通道的飞行特性和纵向周期变距、螺旋桨平均桨距2种操纵舵面的差异，提出基于前飞速度的纵向通道操纵分配策略。分别对2种操纵舵面进行相关的控制律设计，并采用内外环并联的总体控制结构，以兼顾其机动性和稳定性。最后通过MATLAB仿真验证和实际飞行测试，证明该方法能够优化复合式高速直升机的纵向通道控制律，为其飞行控制系统的技术实现提供了理论支持和设计参考。更多还原

【Abstract】 To address the control surface redundancy issue in forward speed control of compound high-speed unmanned helicopters, this study takes a specific model of a compound high-speed unmanned helicopter as the research object and establishes a longitudinal channel dynamic model.The flight characteristics of the longitudinal channel are analyzed, and the differences between two types of control surfaces longitudinal cyclic pitch and the average pitch of the propeller are compared.A control allocation strategy for the longitudinal channel based on forward speed is proposed.Control laws for two types of control surfaces are designed individually, and an integrated control structure with parallel inner and outer loops is adopted to balance maneuverability and stability.Finally, MATLAB simulations and actual flight tests are conducted to validate the effectiveness of the proposed method.The results demonstrate that the proposed approach optimizes the longitudinal control law of the compound high-speed helicopter and provides theoretical support and design references for the implementation of its flight control system.更多还原
