针对一类非线性不确定时滞中立系统,讨论了具有记忆和非记忆混合型反馈保性能控制器设计问题。对于标称系统以线性矩阵不等式(LMI)形式给出一个反馈控制器存在的充分条件。基于上述充分条件给出含不确定项系统的相应结果。所得结果可以利用Matlab/LMI工具箱进行处理。最后,数值例子说明了方法的可行性。
The mixed memory and memoryless guaranteed cost controller design problems for a class of uncertain neutral systems with time-varying delays and nonlinearity are discussed.A sufficient condition for the existence of unperturbed systems is given in terms of linear matrix inequalitis(LMIs).Based on this sufficient condition,the corresponding results of systems with uncertainties are obtained.All the results can be handled by Matlab/LMI toolbox.Finally,a numerical example is illustrated to show the feasiblity of the obtained results.
