2. Differentiate Between Open-loop and Closed-loop Control Systems

Control systems are categorized into open-loop and closed-loop systems based on feedback mechanisms, each serving crucial roles across various engineering applications. Open-loop systems operate without feedback, leading to simplicity and cost-effectiveness but lacking accuracy. In contrast, closed-loop systems use feedback for continuous adjustments, allowing for higher accuracy and stability, but with increased complexity and cost associated with additional components.
