英语词汇“closed loop”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

l. A sequence of control operations or activities in which each depends on the result of the previous one; esp. (more fully closed loop), one in which there is feedback, the result of a later operation being made to affect one earlier in the sequence, usually so as to maintain the output at a desired level.

1945 L. A. MacColl Fund. Theory Servomechanisms viii. 70 This procedure of adding feedback loops to internal parts of a servomechanism is employed frequently when it is necessary to take special steps to insure that the performances of those parts shall be accurate and reliable.

1948 G. S. Brown & D. P. Campbell Princ. Servomechanisms vii. 227 Figure..shows internal loop within a main closed loop.

1954 M. H. Lajoy Industr. Automatic Controls i. 9 The automatic washing machine which operates on a time basis and is not dependent upon whether or not the clothes are clean is an open loop system.

1962 F. I. Ordway et al. Basic Astronautics ix. 366 There are two basic control systems: the open-loop system and the closed-loop system. The open-loop system is familiar to us all. Examples of this are..a light switch, or the horn button on an automobile... In the closed-loop system a portion of the output is sensed and fed back to the input. The input is then altered to achieve a co-ordinated response at the output... A good example is the modern air conditioning system in which room air is fed back to the thermostat control.

1971 J. Z. Young Introd. Study Man vii. 107 Certain cells in the hypothalamus..are very sensitive to slight rises in temperature above the normal (37°C). They then discharge nerve impulses that set in action the mechanisms that cool the body, such as sweating. This cools the blood and switches off the hypothalamus. In order to study such closed-loop feedback systems engineers use the device of ‘opening’ the loop. This has been done..by putting heating electrodes in the hypothalamus and arranging that they keep it at a constant temperature a few tenths of a degree above normal in spite of the cooling blood.
