| 摘 要： | 设计了一种超机动飞行的动态面Backstepping控制方法.新控制律在保留Backstepping"递归"设计步骤的基础上,放弃了参数自适应律;通过构造滑动面变量并根据能达条件,来设计中间虚拟控制信号和最终控制信号;通过在"递归"过程中增加一低通动态滤波器,避免了设计过程中对某些非线性信号的微分,减小了控制律的计算量.数值仿真结果表明,新控制律较简单地实现了超机动飞行时良好的飞机操纵指令信号跟踪,且易于工程实现.

| Abstract: | A dynamic surface Backstepping control for supermaneuverable flight is proposed.In contrast to the basic Backstepping method,our scheme abandons the adaptive laws,and introduces sliding surfaces and reaching conditions to design the virtual control signal and the final control signal.Furthermore,instead of involving the model differentiation,a low pass dynamic filter is used in the two steps Backstepping design,that provides a more simplified control algorithm.The simulation results show that the new scheme... |
