GB/T2900.56—2002
This standard is formulated based on IEC 6000-1 (51):18 International Electrotechnical Vocabulary No. 351: Automatic control (Edition) and is consistent with the international standard in terms of technical content and format. To be consistent with the international standard, the numbering of the terminology and figures in this standard is consistent with IEC 5005 (351). The original version of the international standard IFCH 50 (351): 18 includes the terms and definitions in English and Russian, and also provides the equivalent terms in German, Spanish, Japanese, Dutch, French and Swedish, as well as references in more than 10 languages. This standard also provides the English equivalent terms of the terms, as well as English and American English. This standard is coordinated with the Automation Terms 3 published by the National Science and Technology Conference. The bracketed descriptions of the terms in this standard are the original terms of the adopted international standard IEC 60 (351). The standard terminal number and the standard symbol in brackets indicate the source of the terminology, such as (TS0,1FC2382-28.28.04.C7). Only the clause number indicates the source is the definition of the table in IECi005G, such as (19t.15,01); the "modification" in brackets indicates that the definition of the terminology in this standard has been revised.
Appendix A and Appendix B of this standard are informative appendices. This standard is proposed by the National Technical Committee for Standardization of Electrical Terminology. This standard introduces the National Electrical Terminology Standard. This standard was drafted by the Shanghai Industrial Automation Instrumentation Research Institute and the Mechanical Materials Research Institute. The main drafters of this standard are: Li Minghua, Na Zhiyong and Yang Guan. G8/T2900.562002
IEC Foreword
I (International Electrotechnical Commission) is an international standardization organization composed of national independent committees (IEC centers and national quality committees): IEC's purpose is to promote international cooperation on key industrial electrotechnical standardization issues. IEC is a non-governmental organization that is responsible for coordinating and coordinating the work of standard setting with the International Standards Commission (IEC). It is a non-governmental organization that is responsible for coordinating and coordinating the work of standard setting with the International Standards Commission (IEC). 1) IEC is a formal organization established by the IEC to discuss technical issues concerning international standards. The IEC Technical Committee represents all countries concerned in the formulation of these international standards. These resolutions and agreements express the international consensus on the issues covered. 2) These resolutions are published in the form of standards, reports or guidelines and are made available to the international community in the form of recommended standards. 4) In order to promote international uniformity, the IEC national committees undertake to adopt the maximum possible international standards in their national or regional standards. Any inconsistencies between IEC standards and the corresponding national or regional standards shall be clearly stated in the national or regional standards. 5) IEC does not provide a symbol to indicate its approval. IEC does not accept any responsibility for any claim that equipment conforms to an IEC standard. Please note that the principles underlying international standards may involve patents. IEC recognizes such patents and rights but does not take any responsibility for any comments. International Standard IEC-351 was prepared by Technical Committee 1: "Terminology" and TC55: "Measurement and Control Instruments" Working Group 11. It is based on the first edition of Chapter 31 of the International Code for Standardization (FV). The second edition was published in 1975 and the first revision was published in 1973. The text of this standard is based on the following documents: International Standards Organization
1/1551/Fn15
1/1595/RVD
Details of the approval of this standard may be found in the table indicated in the table. This part of the International Code for Standardization is written in French, English and Russian, with the exception of Spanish, Polish, Swedish and R1. National Standard of the People's Republic of China

CB/T2900.56-2002
1EC60050(351),1998
A group of related elements that can be separated from the environment and form an integral whole within a limited scope. It can be a value or a lack of concepts and habits. For example, a combination of formulas, mathematical methods, comprehensive terms). ? A system is a system that is connected to the same environment and its external system and disconnects the system from the same environment and external systems.
351.11.02 Construction
The relationship between the components of a system.
351.11.033
(Dynamic system) A specific quantity that determines the relationship between the components of a given system. The quantity can be a function of time or a function of the system. Linear system linear6yslem
351-11-04
A system whose behavior is consistent with the principle of superposition.
】The system can be organized in a regular way. 2 In the vocabulary, the behavior does not change with time. 351.11.05 Time invariant system: A system whose behavior is consistent with the principle of displacement.
Note: The formula and its system are not complete. 351.71.06 Multivariable system A system with two or more input variables and one or more output variables (at least one output variable). 351.11.07 Distributed parameter system A system whose spatial distribution is described mathematically by partial differential equations. 351.11.
