Controllability is a concept in control theory that deals with the ability to control or influence a dynamic system or process. It refers to the degree to which a system can be controlled or influenced by an external input or command.

The controllability of a system depends on various factors, including its dynamics, structure, and parameters. A system is said to be controllable if there exists an input signal that can drive its state to any desired point within a finite time. In other words, controllability is the ability to steer the system from one point to another in a controlled manner.

There are several types of controllability, including controllability in the classical sense, which deals with the use of control inputs to influence the system's behavior, and relaxed controllability, which considers the possibility of using constraints or limitations on the control inputs.

The concept of controllability is closely related to that of observability, which deals with the ability to determine the internal state of a system from its output. The controllability and observability of a system are intertwined, and a system that is controllable is not necessarily observable, and vice versa.

Controllability is a crucial aspect of control systems, as it determines the possibilities of controlling or influencing the system's behavior. It has numerous applications in various fields, including robotics, aerospace engineering, economics, and power systems. Understanding the controllability of a system is essential for designing and implementing effective control strategies.

In summary, controllability is a fundamental concept in control theory that deals with the ability to control or influence a dynamic system or process. It has far-reaching implications for the design and operation of control systems in various fields.
