Language:enStatus: Standard
Term: integral action time
Synonym1:
Synonym2:
Synonym3:
Symbol: TI
Definition: for an integral element the reciprocal of the integral action coefficient if its input and output variables are variable quantities of same kind

Note 1 to entry: The integral action time then is given by

T I = 1 K I MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaiqaciWacmGadaGadeaabaGaaqaaaOqaaiaadsfadaWgaaWcbaGaciysaaqabaGccqGH9aqpdaWcaaqaaiaaigdaaeaacaWGlbWaaSbaaSqaaiGacMeaaeqaaaaaaaa@3ACA@

where KI is the integral action coefficient.

Note 2 to entry: The integral action time can also be given as the duration of the time interval required by the step response of an integral element to vary itself about the value of the stepwise variation of its input variable.

Note 3 to entry: This entry was numbered 351-28-21 in IEC 60050-351:2006.
