Controllabile

Controllabile is an Italian adjective meaning able to be controlled or manageable. It can describe devices, processes, or situations that can be directed, influenced, or altered by an agent or control input. The word is formed from the verb controllare (to control) plus the suffix -abile, which marks capability. The corresponding noun is controllabilità (controllability).

In everyday language, controllabile describes a system or situation that can be governed or adjusted. For example, a controllabile drone or a controllabile process implies that its behavior can be steered through appropriate commands or inputs.

In engineering and control theory, a system is said to be controllabile if its state can be driven from any initial state to any desired final state by an appropriate input sequence within finite time. This property, known as controllability, is central to the design and analysis of control systems and is studied using concepts such as the controllability matrix in linear systems and the Kalman criterion for time-invariant cases. The term is common in Italian texts on automation, robotics, and systems engineering.
