约束反推自适应超机动飞行控制律设计

Super-Maneuver Flight Control Design Using Constrained Adaptive Backstepping

基于反推控制理论设计了超机动飞行控制律。考虑到飞机控制变量和状态在幅值、带宽和速度方面的限制,将命令滤波器引入到反推设计过程,简化了标准反推控制对虚拟控制信号求导的复杂计算,仿真结果表明,设计的控制律能控制飞机很好的跟踪过失速机动指令,当出现舵面饱和时,仍能保持参数自适应律收敛和系统稳定。

Super-maneuver flight control was designed based on constrained adaptive backstepping. The backstepping control law made use of command filters to implement any physical or operating constraints on the control variable and states. The tedious analytic calculation of the virtual control derivatives was reduced. The results of digital simulation show that the control law is able to provide accurate tracking, and that the update law remains stable even when saturation of control variable does occur.
