基于模型参考逆方法的鲁棒控制律设计研究

Research on robust control law design based on method of model reference inverse

模型参考逆方法是一种通过对参考模型求逆来进行控制的鲁棒控制方法。基于该方法设计了某型高机动战斗机俯仰姿态鲁棒控制律。在相同控制律下,对系统参数变化、外部输入扰动及不同输入信号情况进行了数值仿真。仿真结果表明,所设计的控制律不仅简单,易于实现,而且有很强的鲁棒性和指令跟踪性能。

The method of model reference inverse is a robust control law design means by the inversion of the reference model.Based on this method,a pitch attitude robust control law was designed for a high maneuver fighter.Then a lot of simulations were performed with the system parameter variables in a big range,external input disturbances and different type input signals under the same control law designed in this paper.It is shown that the control law designed via this method is very simple and practical,and it has advantages of not only strong robustness to system parameter variables and external input disturbances,but also good tracking performance to different type of command signals.
