Root locus is a graphical method used in control systems to analyze how the roots of a system's characteristic equation change as a particular parameter, typically gain, varies. This technique provides insight into the stability and dynamic behavior of feedback control systems, showing the paths that the system poles take in the complex plane as gain changes. It’s essential for understanding how adjustments to system parameters influence performance and stability.
