FAQs

Question: What is a transfer function?
Answer: A transfer function is a mathematical representation that relates the output of a system to its input in the Laplace domain, providing insights into system behavior.

Question: How do I determine the stability of a system?
Answer: Stability can be determined by analyzing the poles of the transfer function; if all poles have negative real parts, the system is stable.

Question: Why is time response important in control systems?
Answer: Time response helps in understanding how a system reacts over time to various inputs, which is essential for designing effective control strategies.
