汽轮机 DEH 伺服系统阀位反馈信号可靠性设计与分析

Reliability Design and Analysis of the Valve Feedback Signal for Turbine DEH Servocontrol System.

根据可靠性动、静态冗余技术提出了一种提高伺服机构可靠性的设计方案，大大减小了因阀位反馈值测取通道发生故障而引起的执行机构误动作的可能性，从而大大提高了整个汽轮机电－液调节系统的可靠性。

Abstract According to the technique of dynamic and static redundancy, this paper designs a kind of method which can increase the reliability of servocontrol. The desighn can avoid error action of servocontrol, and the error action is sometimes aroused by fault access of valve feedback value, and so the design increases the reliability of entire turbine digital electro hydraulic control system.
