4. Linear System by Meiling CHEN4 Definition A linear system is said to be completely controllable if, for all initial times and all initial states, there exists some input function (or sequence for discrete systems) that drives the state vector to any final state at some finite time. A linear system is said to be completely observable if, for all initial times, the state vector can be determined from the output function (or sequence), defined over a finite time.
