WebControl Systems - Feedback. If either the output or some part of the output is returned to the input side and utilized as part of the system input, then it is known as feedback. Feedback plays an important role in order to improve the performance of the control systems. In this chapter, let us discuss the types of feedback & effects of feedback. WebThe classical stability criterion applies to this loop gain and we require that either (a) the phase of the loop gain is already beyond -360 deg if the loop gain magnitude reaches 0 dB or (b) the loop gain magnitude is smaller than 0 dB at that frequency where the loop gain phase is crossing the -360deg (0 deg) line. browser a confronto
