摘要
将H∞控制理论应用于飞机俯仰角控制系统的设计。首先,按照干扰抑制原理将控制系统的设计转化为H∞标准控制问题;然后,通过选择适当的加权函数构造出广义的被控对象;最后,采用Matlab的鲁棒控制工具箱求得俯仰角控制器。频域分析和时域仿真均表明,所设计的控制系统具有较好的标称性能和鲁棒性能。
The H∞ control theory is applied to the design of aircraft pitching angle control system.Firstly,the control system design is converted to the H∞ standard control problem based on the interference suppression principle.Secondly,augmented controlled object is constructed by selecting proper weighting functions.Finally,the Matlab robust control tool box is used to calculate the pitching angle controller.Analysis in frequency domain and simulation in time domain show that the control system has good nominal and robust performance.
