一类参数不确定线性广义系统的保性能控制

Guaranteed cost control for a class of linear descriptor system with parametric uncertainty

研究了一类含有时变、范数有界参数不确定线性广义系统的保性能控制问题.在给定的二次型性能指标的前提下,基于线性矩阵不等式方法,给出了状态反馈保性能控制律的设计方法.最后,利用LMI工具箱给出数值例子,说明了设计方法的有效性.

Discussed guaranteed cost control for a class of linear descriptor system with time-change,norm-bounded and parametric uncertainty.With the quadratic cost function,gave the method of guaranteed cost controllers of state feedback by linear matrix inequality.In the end,the numerical example shows the validity of our method via the LMI-box.
