Abstract :
The paper proposes an algorithm to identify state space noise model from closed-loop system via the numerical algorithm for subspace state space system identification, N4SID. It works well on both stable and unstable systems with serious noises and can derive quite accurate plant and noise models together from closed-loop measurement signals
