Root Locus Technique

The Root Locus Technique is a graphical method used in control systems to analyze how the stability and behavior of a system change as a specific parameter, typically gain, varies. It plots the possible locations of the system’s poles (solutions that determine stability) on the complex plane, showing how these points move with changing gain. This visual helps engineers understand the stability margins and design controllers to ensure the system remains stable and performs as desired across different conditions. Essentially, it illustrates the relationship between system parameters and stability in a clear, visual format.
