本文研究了一类具有时变时滞、外部干扰和控制饱和的动态系统的鲁棒指数镇定问题。一个线性无记忆状态反馈控制器的合成，以保证有一个域的容许初始条件，从考虑的系统的所有解决方案，以预先指定的收敛速度指数收敛到一个球。该问题被表述为一个两步优化问题，矩阵不等式约束，以扩大球的大小的可容许的初始条件。
This brief paper deals with the problem of robust exponential stabilization of a class of dynamic systems subject to time-varying delays, external disturbances and control saturation. A linear memoryless state feedback controller is synthesized to guarantee that there is a domain of admissible initial conditions from which all solutions of the class of systems considered converge exponentially to a ball with a prespecified convergence rate. The problem is formulated as a two-step optimization problem with matrix inequality constraints to enlarge the size of the ball of admissible initial conditions.
