摘　　要：本文在对CH-46纵列式双旋翼直升机在悬停时刻线性化模型进行分析的基础上,采用状态反馈线性二次型调节器(LQR)技术设计了该直升机悬停控制律,使得直升机能够获得满意的性能指标。以该直升机模型、LQR调节器构成闭环仿真系统进行控制律验证仿真;仿真结果表明,所设计的LQR调节器能较好地实现直升机悬停功能,在工程上也比较容易实现。On the basis of the simulation model of the CH-46 helicopter,A hovering control law,which is designed by means of the linear quadratic regulator（LQR） of state feedback,is used to satisfy helicopter hovering performance.The digital simulation is accomplished based on the helicopter flight control system including LQR regulator.The simulation results demonstrate that the hovering control law designed is effective to carry out the hovering function.In addition,the hovering control law can put into practice easily.
