摘　　要：双螺旋桨推进复合式直升机具有可变飞行模式,过渡段是实现不同飞行模式转换的必经阶段,且两侧螺旋桨的不对称效果加剧横航向耦合,为保证复合式直升机过渡段的飞行安全,设计横航向姿态解耦控制系统。针对复合式直升机过渡飞行阶段存在的控制方式转换与横航向通道间操纵耦合问题,制定了以操纵功效为约束的控制方式线性过渡策略,基于显模型跟踪解耦控制理论设计了控制阵解耦的姿态控制器,构建了横航向姿态解耦控制系统仿真模型。仿真结果表明:该控制系统可以有效保证复合式直升机控制方式平稳转换,并实现横航向通道解耦控制。The dual-propeller propulsion compound helicopter has variable flight modes.The transition phase is a necessary stage to realize the conversion of different flight modes,and the asymmetry effect of propellers on both sides intensifies the coupling between lateral and heading attitude.In order to ensure the compound helicopter flight safety in transition flight phase,a lateral and heading attitude decoupling control system is designed.To solve the problems of control mode conversion and manipulation coupling between lateral and heading channels in the transition flight phase of compound helicopter,a linear transition strategy of control modes taking control efficiency as the constraint is formulated.Based on the explicit model tracking decoupling control theory,the attitude controller with control matrix decoupling is designed,and the simulation model of the lateral and heading attitude decoupling control system is constructed.The simulation results show that the control system can effectively ensure the smooth transition of the compound helicopter control modes and realize the lateral and heading channel decoupling control.
