摘　　要：给出一种饱和系统鲁棒稳定性的分析和设计方法.通过对不确定系统的H∞优化过程的分析,并根据其反馈控制原理,按全部和部分输入超过限制分别考虑不同指标下的优化计算问题,得到了输入受限制条件下的3种Riccati方程.飞行控制器设计和仿真结果表明,采用该方法可给出满意的控制效果.A method for designing robust controller of processes subject to saturation nonlinearities is presented. Based on the principles of optimal H∞ control, characteristics of input constrains are considered in the computations of Lyapunov weighted matrices. To simplify the optimal process, different descriptions for input weighted matrix of systems is discussed and three Riccati equations are improved for solving H∞ control problems. An aircraft landing control design shows that the new algorithm gives the satisfactory responses.
