control.obsv
- control.obsv(A, C, t=None)[source]
Observability matrix.
- Parameters
- A, Carray_like or string
Dynamics and output matrix of the system.
- tNone or integer
Maximum time horizon of the controllability matrix, max = A.shape[0].
- Returns
- O2D array
Observability matrix.
Examples
>>> G = ct.tf2ss([1], [1, 2, 3]) >>> C = ct.obsv(G.A, G.C) >>> np.linalg.matrix_rank(C) np.int64(2)
