ObservabilityMatrix

ObservabilityMatrix[ss]
gives the observability matrix of the StateSpaceModel object ss.
  • The state-space model ss can be given as StateSpaceModel, where a, b, c, and d represent the state, input, output, and transmission matrices in either a continuous-time or a discrete-time system:
continuous-time system
discrete-time system
  • The observability matrix is computed as , where is the dimension of the square state matrix a.

The observability matrix of a continuous-time system:
A system is observable if and only if its observability matrix has full rank:
The observability matrix of a discrete-time system does not depend on the sampling period:
