State Space

Definition

State space refers to a mathematical representation of all possible states in which a dynamic system can exist, encompassing both the current conditions and variables that define the system's behavior over time. Each point in this space corresponds to a specific configuration of the system, allowing for the analysis and control of dynamic systems. This concept is crucial for understanding how systems evolve, interact, and can be manipulated, particularly when dealing with complex, multidimensional systems.
