Control Theory

Definition

Control theory is a mathematical framework used to analyze and design systems that can regulate their behavior in response to changes in their environment. This concept is crucial for understanding how biological systems maintain homeostasis and respond to stimuli, which is essential in fields like neuroscience and systems biology, as it allows researchers to model complex interactions and feedback loops within living organisms.
