error signal

[′er·ər ‚sig·nəl] (control systems) In an automatic control device, a signal whose magnitude and sign are used to correct the alignment between the controlling and the controlled elements. (electricity) error voltage (electronics) A voltage that depends on the signal received from the target in a tracking system, having a polarity and magnitude dependent on the angle between the target and the center of the scanning beam.

error signal

A voltage whose magnitude is proportional to the difference between an actual and a desired position. In radar use, error signals are obtained from selsyns and automatic gain control circuits. The error signals are used to control servo systems, so that the resultant motions tend to correct the error.
