Separation principle

The separation theorem is a fundamental set for the design of controllers with state observers. He says that the eigenvalues ​​of a state regulation without an observer will not be moved when the state variables can be reconstructed by an observer. The poles of the observer come to the poles of the state control loop added without an observer. This can initially be designed without taking into account the necessary observer of the controllers. This is then added in a second design step.

Furthermore, it can be shown that the leading behavior is determined only by the poles of the scheme, while the disturbance response is determined by the poles of the system and the observer.
