An Impulse System is a concept in control theory that describes how a system responds to sudden changes or inputs. It focuses on the immediate effects of a brief input, often represented as a spike or pulse. This system is crucial in understanding how various processes react to quick disturbances, such as in electronics or mechanical systems. In practical applications, an Impulse System can be seen in areas like signal processing and robotics. Engineers use this concept to design systems that can quickly adapt to changes, ensuring stability and efficiency in operations.
