Controllability

Controllability refers to the ability to influence or change a system's behavior or state through inputs or actions. In practical terms, if a system is controllable, you can direct it to reach a desired condition or outcome by applying appropriate control signals. For example, a thermostat is controllable because you can set its temperature, and it adjusts the heating or cooling accordingly. In engineering and control theory, assessing controllability helps determine whether a system can be guided as needed, ensuring effective management and decision-making.
