Nonlinear Control Theory

Nonlinear Control Theory is a branch of engineering focused on managing systems whose behavior doesn't follow straight-line, predictable patterns. Unlike simple systems, nonlinear systems can behave in complex ways, like oscillating or responding unpredictably to inputs. This theory develops strategies to design controllers—rules or algorithms—that help such systems perform desired tasks reliably, despite their complexity. It’s essential in fields like robotics, aircraft, and energy systems, where understanding and managing nonlinear behaviors ensures safety, efficiency, and stability in real-world applications.
