How do you determine controllability and observability?

By using Gilbert's test we can directly tell about controllability and observability of a system. This test can be applied to the systems which are in Normal form (DCF / JCF).

How do you find the controllability of Gramian in Matlab?

Description. Wc = gram( sys ,'c') calculates the controllability Gramian of the state-space ( ss ) model sys . Wc = gram( sys ,'o') calculates the observability Gramian of the ss model sys . Wc = gram(___, opt ) calculates time-limited or frequency-limited Gramians.

How do you know if a matrix is controllable?

Controllability MatrixEdit

A system is controllable or "Controllable to the origin" when any state x₁ can be driven to the zero state x = 0 in a finite number of steps. If the second equation is not satisfied, the system is not .
