Study Notes
Controllability and Observability
- Controllability and observability represent two major concepts of modern control system theory.
- Controllability is necessary to be able to do whatever we want with the given dynamic system under control input.
- Observability is necessary to see what is going on inside the system under observation.
Controllability
- A process G is said to be controllable if every state variable x of G can be affected or controlled in finite time.
- This is achieved by some unconstrainted control signal u(t).
- Controllability means that every state variable x of G can be affected in finite time.
Observability
- A process G is said to be observable if every state variable x of G eventually affects some of the outputs y of the process.
- Observability means that every state variable x of G eventually affects some of the outputs y of the process.
