摘　　要：指出当前流行的提升法并不适用于采样控制系统的H∞综合.提出了一种新的采样控制系统的离散化H∞设计方法.并结合扰动抑制问题,指出应该是一种有约束的H∞设计,给出了鲁棒扰动抑制问题中离散化H∞设计的权函数计算方法.方法简单直观,物理概念清楚,且便于验算.文中附有算例.It is pointed out that the popular lifting technique is not suitable for H∞ synthesis of the sampled - data control system. A novel discretization method of H∞ design for the sampled -data control system is proposed and it is pointed out that the disturbance attenuation problem should be a constrained H∞ optimal design. The determination of weighting functions of the discretization H∞ design for the robust disturbance attenuation problem is discussed in detail. This method is simple, intuitive, has clear physical meanings, and it can be easily verified. Several examples are given.
