What is root locus? State one application for root locus.

Solution

Root locus : It is useful to determine the locus of roots in s-plane as a parameter varied since the roots is a function of the system’s parameter.

The root locus technique is a graphical method for sketching the locus of roots in the s-plane as a parameter is varied and has been utilized extensively in control engineering practice.

It provides the engineer with a measure of the sensitivity of roots of the system a variation in parameter being considered .

Applications :  The root locus technique for the design of a feedback control system of an F-104A aircraft.
