摘要: 针对应用广泛的单调节参数工业汽轮机,提出了一种高工作可靠度的新型容错控制系统,它由两个电液通道和1个虚拟电液通道组成。它的容错对象是整个电液通道,而非单个元器件。正误码判断基于虚拟通道,而不采用三中取二。

Abstract: In order to improve the reliability of industrial steam turbine regulating system with one control parameter, a new type of fault tolerant control system is developed. The system is composed of two real electro-hydraulic channels and one visual electro-hydraulic channel, its fault tolerant object is not the single element, but the whole electro-hydraulic channel, and channel selection is not based on two out of three voting, but the output of the visual channel.

Key words: Electro-hydraulic control, Fault tolerant, Steam turbine, Visualization
