Observers in Linear Systems Theory
Observers are dynamical systems which process the input and output signals of a given dynamical system and deliver an online estimate of the internal state of the given system which asymptotically converges to the exact value of the state. For linear, finite-dimensional, time-invariant systems, observers can be designed provided a weak observability property, known as detectability, holds.
