36、e by manufacturers to determine the performance of their products and by users, or independent testing establishments, to verify manufacturers performance specifications. Part 2 of the standard, IEC Publication 546-2, describes a limited series of tests which may be used as acceptance tests. The tes
37、t conditions specified in this standard, for example the range of ambient temperatures, power supply, etc., shall be used when no other values are agreed upon by the manufacturer and the user. The tests specified in this standard are not necessarily sufficient for instruments specifically designed f
38、or unusually arduous duties. Conversely, a restricted series of tests may be suitable for instruments designed to perform within a limited range of conditions. It will be appreciated that the closest liaison should be maintained between an evaluating body and the manufacturer. Note shall be taken of
39、 the manufacturers specifications for the instrument when the test program is being decided, and the manufacturer should be invited to comment on both the test program and the results. His comments on the results should be included in any report produced by the testing organization. 1 Scope This sta
40、ndard applies to pneumatic and electric industrial-process controllers using analogue continuous input and output signals which are in accordance with current International Standards.1) It should be noted that while the tests specified herein cover controllers having such signals, they can be applie
41、d in principle to controllers having different but continuous signals. These methods of evaluation may also be employed on devices which internally use digital concepts and elements provided the input and output signals are conventional analogue signals. 2 Object This standard is intended to specify
42、 uniform methods of test for evaluating the performance of industrial-process controllers with analogue input and output signals. When a full evaluation in accordance with this standard is not required, those tests which are required shall be performed and the results reported in accordance with tho
43、se parts of the standard which are relevant. The testing program should be subject to an agreement between manufacturer and user, depending on the nature and the extent of the equipment under consideration. 1) IEC Publications 381 and 382.

45、e equations are valid for controllers with no interaction between the factors Kp, KI and KD. The equation for idealized controllers with interaction taken into account may be written as: In this equation, A is the interaction factor that depends on the structure of the controller. It can often be wr

48、 IEC Publication 50 (351). NOTE 3This standard is limited to P, PI, PD or PID controllers. NOTE 4The factors Kp, KI and KD may have the sign “plus” or “minus”; it is usual to associate “direct action” with the positive sign and “reverse action” with the negative sign. NOTE 5Symbols with prime (Kp, T
49、I, TD) represent nominal values, in contrast to effective values. NOTE 6Integral-action time constant and derivative-action time constant refer only to pure integral or derivative-action controllers IEC Publication 50 (351). There are controllers with still other structures, for example where the differentiation is applied only to the measured value x, not to (x w). Equation (3) becomes thereby: 3.2 Limitations The equations describing the performance of an actual controller are usually different from equat
