Root locus

Root locus is a way of studying how a system responds to changes in its environment. It is like a map of how the system will move or change when it is "stressed" in different ways. You can look at the map to predict how the system will respond when it is given different types of input. For example, if you have a system that produces a sound, you can look at the root locus map and see how the sound will change when you give it a louder input sound. This can help you figure out how to make your system sound better.
