The root locus of a system is the locus of its closed loop roots in the s-plane, parameterized using the variable K, which can represent either an open loop gain or an unknown plant parameter. Since the closed loop roots determine the time response characteristics of a controlled system, the root locus can be used as a graphical means of exploring the systems stability and response as K varies. It can also be used to design a controller capable of achieving a desired response. Here root locus analysis and design techniques are presented.
