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.
