研究了一类不确定时滞系统的保性能控制问题，其不确定性不仅存在于系统矩阵，而且存在于控制器的增益中。
The problem of guaranteed cost control for a class of uncertain time-delayed systems was addressed. The uncertainties existed both in the systematic matrix, and in the controller gain.
利用模糊系统对不确定性函数进行逼近，将获得的模糊系统函数作为系统不确定性界函数。
The fuzzy system is used to approximate the system uncertain function, and the fuzzy system function obtained is taken as system uncertainty boundary function.
针对控制系统中应用十分广泛的不确定性问题进行了研究，主要研究了含范数有界参数不确定性中立型多延迟微分系统的鲁棒稳定性。
Research is done on the robust stability of multi -delay differential systems of neutral type subject to norm -bounded parameter uncertainty that played important roles in the control theory.
