Dynamic response refers to how a system reacts to changes or disturbances over time. This concept is often applied in fields like engineering, physics, and economics, where systems must adapt to varying conditions. For example, in mechanical systems, dynamic response can describe how a structure behaves under loads or vibrations. In control systems, dynamic response is crucial for maintaining stability and performance. It involves analyzing how quickly and accurately a system can return to its desired state after a disturbance. Understanding dynamic response helps engineers design more efficient and reliable systems, ensuring they perform well under different scenarios.
