This paper proposes a serial interface for inputting pulse sequence and several algorithms for processing sampled data that are used to implement the tasks of feedback and command setting in a digital system.The algorithms are able to reduce the requirment for the number of counter bits in the interface and get both feedback variable of displacement and velocity with a single pulse sensor, a single feedback channal and the above mentioned interface. All of these algorithms are fast and suitable for the application...

This paper proposes a serial interface for inputting pulse sequence and several algorithms for processing sampled data that are used to implement the tasks of feedback and command setting in a digital system.The algorithms are able to reduce the requirment for the number of counter bits in the interface and get both feedback variable of displacement and velocity with a single pulse sensor, a single feedback channal and the above mentioned interface. All of these algorithms are fast and suitable for the application of some digital rea-time data processing and control systems. The system with such interface and algorithms will have one important superiority of economy.

本文提出一种实现数字量反馈、给定方案的脉冲序列串行输入接口及其采样数据处理算法。这些算法能降低对接口中计数器位数的要求;靠一个脉冲式传感器、一条反馈通道和一个这样的接口,就可以求取位移、速度两种反馈量。这些算法的速度都很快,适合于一些实时的数字数据处理、控制系统。采用这种接口和算法的系统,经济性好是其主要优点。

In this paper,the existence of the solution for the Most Economical Information Structure(MEIS)problem is discussed.A criterion for determining the fixed modes as well as their multiplicities,applicable to arbitrarily restricted feedback structure,is then given.This criterion provides the possibility to evaluate the contributions of all single feedback elements and their combinations to the removing of the open-loop poles and thus furnishes the necessary information for synthesizing the MEIS.On this basis,the...

In this paper,the existence of the solution for the Most Economical Information Structure(MEIS)problem is discussed.A criterion for determining the fixed modes as well as their multiplicities,applicable to arbitrarily restricted feedback structure,is then given.This criterion provides the possibility to evaluate the contributions of all single feedback elements and their combinations to the removing of the open-loop poles and thus furnishes the necessary information for synthesizing the MEIS.On this basis,the authors present a recursive algorithm for synthesizing MEIS and propose the design procedure of decentralized control systems with the MEIS.Finally,a numerical example is given for illustration.

本文首先讨论了最经济分散信息结构解的存在性问题,然后给出一个适用于任意反馈结构限制并能确定固定模代数重数的判据.这个判据确定了任意单个反馈元及其组合对移动开环极点的贡献,从而提供了综合最经济分散信息结构所必须的基础信息.在此基础上,作者提出递推型的最经济信息结构综合算法以及在此结构下分散控制系统的设计过程,并以具体算例作了说明.

The “electro pneumatic” remote control mode of single feedback closed loop controlling has been widely adopted in the remote control device of V390 Series Marine Diesel Engine.The features of this remote control device is analyzed at first in the paper.It is pointed out that the defect of pure time delay existing in the pneumatic pipelines between E/P converter and servo cylinder causes the unstability in the low speed region of main diesel engine itself and so called “oscillation” phenomenon.The results of...

The “electro pneumatic” remote control mode of single feedback closed loop controlling has been widely adopted in the remote control device of V390 Series Marine Diesel Engine.The features of this remote control device is analyzed at first in the paper.It is pointed out that the defect of pure time delay existing in the pneumatic pipelines between E/P converter and servo cylinder causes the unstability in the low speed region of main diesel engine itself and so called “oscillation” phenomenon.The results of calculation analysis and testing actual engine indicate that a full function type of speed regurator with pneumatic input interface unit should be chosen to make the configuration of remote control device and the engine converting procedures simplified.In this way “two time adjustments” of remote control device will be achieved to eliminate the “oscillation” phenomenon in the low speed adjustment region of main diesel engine.Then,the thermal and mechanical loads will be effectively controlled.

V390 系列主柴油机遥控装置,广泛采用单回路闭环控制的“电-气”遥控方式。首先分析该遥控装置的特点,然后指出电/气转换器至伺服气缸之间的气动传输管路存在纯时延缺陷,造成主柴油机自身低速区的不稳定性,易引起“振荡”现象。计算分析与实机调试的结果表明,为V390 系列船用主柴油机应该选用一种带输入气压接口单元的全制式调速器,这样,可简化遥控装置的结构体系进而简化轮机转换的操作程序,实现遥控装置的“二次调节”,避免主柴油机在低速调节区的“振荡”现象,并能有效控制其热负荷和机械负荷
