文中针对分布参数结构特性设计了滤波增广结构，对增广系统设计带观测器的状态反馈构成控制器。

The Parallel Filtering Control is brought forward in this paper: a filter designed for the structure is used to augment the system, based on which the observer is built for state feedback.

然后考虑含有故障的时滞系统，设计了故障诊断滤波器，将故障诊断滤波器与原系统组成增广系统，增广系统中包含时滞系统的执行器故障和传感器故障。

Secondly, a filter for filtering the fault of time-delay system is designed, an augmented system that includes the actuator and the sensor faults is proposed.
