Define controllability.
Understand the Problem
The question is asking for the definition of the term 'controllability', which is a key concept in control theory and various fields such as engineering and economics. To answer this, one would explain what controllability means in these contexts.
Answer
Controllability is the ability of a control system to move a system from any initial state to any desired final state within a finite time period, given appropriate control inputs.
Controllability is the ability of a control system to move a system from any initial state to any desired final state within a finite time period, given appropriate control inputs.
Answer for screen readers
Controllability is the ability of a control system to move a system from any initial state to any desired final state within a finite time period, given appropriate control inputs.
More Information
In control theory, checking the controllability of a system is crucial to design effective controllers. The controllability can often be tested using the controllability matrix.
Tips
A common mistake is to confuse controllability with observability. While controllability is about controlling the state of the system, observability is about being able to infer the state of the system from its outputs.
