Feedback control – is an operation which, in the presence of disturbances, tends to reduce the difference between the output of a system and the reference input (i.e., minimize the error). C. S. George Lee () Introduction to Control Systems January 11, 2010 19 / 26 Introduction to Control Systems Feedback control system – is one which tends to maintain a prescribed relationship between the output and the reference input by comparing these and using the difference as a means of control. Servomechanism – is a feedback control system in which the output is some mechanical position, velocity, or acceleration.
