摘　　要：为了实现直升机旋翼转速在宽广范围内连续变化且涡轴发动机连续提供输出轴功率,采用1种扭矩序列转移控制方案来实现该传动链。通过2台涡轴发动机和2台多级变速器与旋翼协调工作,发动机依次连接或脱开旋翼,提供旋翼转速大范围内变化,并提供旋翼连续变化的功率。在扭矩转移过程中,针对发动机扭矩强扰动问题设计了鲁棒LMI控制器+ADRC扭矩前馈补偿控制器,最后基于直升机/发动机综合模型进行数值仿真,验证了扭矩转移方案的可行性。仿真结果表明:在转移过程中的扭矩强扰动对发动机动力涡轮转速的影响较小,旋翼转速可以实现较大范围内的快速平滑变化。A sequential shifting algorithm was proposed for changing the helicopter rotor＇s speed in a large variation and providing continuous output power to the rotor. Two turbo-shaft engines and two multi-speed gearboxes coordinate with the rotor that facilitate a wide rotor speed variation and provide continuous torque to the rotor. Aiming at the problem of turbo-shaft engine＇s torque disturbance, the robust ALQR controller combined with ADRC torque feed forward compensation was designed in the process of shifting. Some numerical simulations are carried out to verify the feasibility of the shifting algorithm based on the integrated helicopter/engine model. The simulation results show that the torque disturbance has little influence on engine power turbine speed in the process of torque shifting, and the rotor speed can perform rapid and smooth changes at larger range.
