Nonlinear control systems

Nonlinear control systems are systems where the relationship between input and output is not a straight line; instead, it varies in complex ways. Unlike linear systems, which can be easily predicted and analyzed, nonlinear systems can exhibit behaviors like sudden changes or oscillations. Examples include robots, aircraft, and traffic systems. Understanding and controlling these systems is crucial for ensuring they behave as intended, especially under different conditions. Engineers use specialized techniques to design controllers that can handle these complexities, ensuring stability and desired performance even when conditions change or become unpredictable.
