In this paper a new theoretic model of automatic fault diagnosis for the digital systems is proposed, in which the set of test outcomes tallies with the modulo-two operation. The necessary and sufficient conditions of fault syndrome in this model have been discussed. It has been proved that any digital system which is suited to modulo-two model has the one-step fault diagnosability, if the number of fault units is less than the half of total units. It is shown that Determing the most likely consistent fault...

In this paper a new theoretic model of automatic fault diagnosis for the digital systems is proposed, in which the set of test outcomes tallies with the modulo-two operation. The necessary and sufficient conditions of fault syndrome in this model have been discussed. It has been proved that any digital system which is suited to modulo-two model has the one-step fault diagnosability, if the number of fault units is less than the half of total units. It is shown that Determing the most likely consistent fault sets is equivalent to solving a modulo-two linear programming problem. Based on this analysis, the author has gotten an effective method and its APL program for correctly ditect consistent fault sets, and proved that the space-time complexity of this algorithm is linear. Finaly, this model has been extended to probabilistic fault diagnosis. In fact, there are some advantages in modulo-two model over the others.

本文提出了数字系统故障自动诊断的一个新的理论模型,此模型中的测试记录符合模2运算。文中讨论了模2模型故障症候的充分和必要条件,证明了任何适合此模型的系统都是在故障单元少于半数情况下一步故障可诊断的。进而指出,确定最大可能相容故障集与解模2线性规划问题是等价的。在此基础上,给出了一个求相容故障集的有效算法以及它的APL程序,并且论证了此算法的时间和空间的复杂性都是线性的。最后,将此模型推广到了随机故障诊断。事实表明此模型与其它模型相比有较多的优点。

A new precision method to measure microwave network parameters is reported in this paper. The reported five-port is developed and simplified from the basic concept of six-port[1,2] but with much simpler and quite defferent design considerations. The ambiguity problem in five-port reflectometer can be avoided via suitable hardware design for any posible value of reflection coefficient (passive or active load). The design considerations, calibration and some experimental results of a simple five-port reflectometer...

本文介绍微波网络参数的一种新的精确测量方法。其精髓是发挥电子计算机的软件功能,降低对微波“硬件”的精度和复杂性的要求,并通过一个校准过程,消除微波硬件不理想之类的误差。文中介绍的“五端口”是从正被广泛重视的“六端口”反射仪发展而来的,但更为简单、经济。理论分析及初步实验结果证明,一个恰当设计的五端口反射仪,可用于任何复反射系数(其幅值可以大于或小于1)的实时精确测量。

Gas turbine is a nonlinear, multi-input and multi-output powersystem. The increasing of the number of shafts and the number of control paramet-ers, togather with their corresponding control loops, make the gas turbines as acontrol object more and more complicate. This paper gives a study of the dynamicbehaviour of split shaft gas turbines with regenerator and adjustable nozzles by themodern control theory. With the detailed consideration of the physical phenomena,which take place in transient response, five differential and six algebraic equationsdescribing the dynamic behaviour are deduced, finally, through some special transfor-mation, a mathematical model of split shaft gas turbines in state-space form isobtained. On the basis of this state-space mathematical model, this paper presentsa common computer programm for the dynamic study of different split-shaft gasturbines with different control rules. This mathematical model may also be used forthe optimal control of split-shaft gas turbines.

燃气轮机是一个复杂的非线性、多输入一多输出系统。随着燃气轮机轴数的增加(分轴、双轴、叁轴…),被调节量的增多和调节规律的复杂化(从只调节燃料量到同时调节燃料量、可调喷嘴、可转导叶…),以及在系统中包括多个调节回路,更增加了分析的复杂性。本文用现代控制理论对带回热器、具有可调喷嘴的分轴燃气轮机进行分析研究,列出了描述分轴机组的微分方程与代数方程,经变换后得到了分轴机组的状态空间数学模型。在此基础上,用子系统组合的方法编制了适合于不同分轴机组和不同调节规律动态分析的通用程序。此数学模型亦可用于分轴机组的最优控制。
