推力矢量飞机操纵指令的协调分配

Coordination of Control Deflector Commands to Thrust Vectored Aircraft

研究了飞机带推力矢量系统、出现冗余操纵面时，合理分配操纵指令的问题。基于非线性动态迈控制提出了饱和策略和最小操纵策略，并得出了相应的指令解。闭环仿真结果证实了其可行性。如果能够放宽尾喷管的实际限制、允许持续使用推力矢量，那么最小操纵策略将具有更好的控制效果。

Thrust vectoring technology has been and is rapidly becoming increasingly important in future-generation fighter plane. As yet, no relatively detailed theoretical discussion about its control law has appeared in the open literature. We now present our theoretical researchon it.To fly into desired situations, the generally redundant control deflectors of thrust vectored aircraft are automatically commanded, so that the complex control interactions become transparent to the pilot' Based on tile nonlinear dynamic inversion control technique, two command apportioning strategies are proposed, namely saturation-then-augment and minimal controlling I then related equivalent control derivatives and decoupled linear relations of output and input are obtained respectively. Numerical simulations in the case of closed-loop dynamics show that the minimal controlling strategy can achieve better response qualities when continuous thrust vectoring is allowed.
