Controllability is the ability to control the state of the system by applying specific input whereas observability is the ability to measure or observe the system's state. Observable if the observability matrix mo =[ctatc(at)2ct]t has full column rank (rank = n). The concept of controllability refers to the ability of a controller to arbitrarily alter the functionality of the system plant

Controllability Observability State Space Representation State Space Model And

The idea is that we measure the state of the system in some way and adjust the inputs to modify the state behaviour Controllable if the controllability matrix mc =[baba2b] has full row rank (rank = n, where n is the number of states) However this implies that we can both observe the states and control them

As for observability, we see that controllability is really all about a and b, without any role played by the output matrices c or d

As such, instead of saying whether the system is controllable or not, we. There is an important relationship between controllability and observability called the duality principle It states that the system (a, b) is controllable if and only if the. Controllability is another geometric property of a system, describing the ability to \drive the system states to arbitrary values through the control input

Its dual notion of observability describes the ability to infer. Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs In control theory, the observability and controllability of a linear system are.
