Questions & Step-by-Step Solutions

What is the root locus of a system used for?
  • Step 1: Understand that a system can be represented by a mathematical equation, often in the form of a transfer function.
  • Step 2: Recognize that the roots of this equation (called poles) determine the behavior of the system.
  • Step 3: Learn that the gain of the system can be adjusted, which affects the location of these poles.
  • Step 4: The root locus is a plot that shows how the poles move in the complex plane as the gain changes.
  • Step 5: Use the root locus to analyze the stability of the system; if poles are in the left half of the complex plane, the system is stable.
