What is the primary purpose of using a lead compensator in control systems?

Step 1: Understand what a lead compensator is. It is a device used in control systems to modify the behavior of the system.
Step 2: Learn about phase margin. Phase margin is a measure of how stable a control system is. A higher phase margin means better stability.
Step 3: Recognize that a lead compensator helps to increase the phase margin. This means it makes the system more stable.
Step 4: Know that improving stability also helps the system respond better to changes, which is called transient response.
Step 5: Conclude that the primary purpose of using a lead compensator is to enhance stability and improve how the system reacts to changes.
