Linearization is the process of approximating a nonlinear system by a linear model around a specific operating point, which simplifies analysis and control design. This technique is widely used in mathematics, physics, and engineering to make complex systems more tractable by focusing on local behavior near equilibrium points.

A linear model is a mathematical representation that assumes a linear relationship between input variables and the output variable, often used for prediction and analysis in statistics and machine learning. It is characterized by its simplicity and interpretability, making it a foundational tool for understanding more complex models.

Complex systems are characterized by intricate interactions and interdependencies among their components, leading to emergent behavior that cannot be easily predicted from the properties of individual parts. These systems are often adaptive, dynamic, and exhibit non-linear behaviors, making them challenging to analyze and manage.

local behavior

Equilibrium points are states in a dynamic system where all forces are balanced, and the system experiences no net change. They are critical in understanding system stability and behavior over time, as small perturbations can either return the system to equilibrium or lead to significant deviations.
