Control System 면접 질문과 답변
Ques 1. What is the difference between an open-loop and a closed-loop control system?
In an open-loop system, the control action is independent of the output, while in a closed-loop system, the control action depends on the feedback from the system's output.
Ques 2. Explain the concept of feedback in a control system.
Feedback is the process of using the output of a system to modify the input, allowing the system to regulate itself and maintain the desired output.
Ques 3. What are the advantages of closed-loop control systems over open-loop systems?
Closed-loop systems are more accurate, stable, and able to adapt to changes and disturbances compared to open-loop systems.
Ques 4. Define a transfer function in the context of control systems.
A transfer function is a mathematical representation of the relationship between the input and output of a linear time-invariant system in the frequency domain.
Ques 5. What is the significance of the Laplace transform in control system analysis?
The Laplace transform is used to analyze linear time-invariant systems in the frequency domain, simplifying differential equations into algebraic equations for easier analysis.
