ObservabilityMatrix

ObservabilityMatrix[ssm]
gives the observability matrix of the state-space model ssm.

DetailsDetails

  • For a standard state-space model:
  • continuous-time system
    discrete-time system
  • The observability matrix is given by , where is the dimension of .
  • For a descriptor state-space model:
  • continuous-time system
    discrete-time system
  • The slow and fast subsystems can be decoupled as described in KroneckerModelDecomposition:
  • slow subsystem
    fast subsystem
    output equation
  • ObservabilityMatrix returns a pair of matrices , based on the decoupled slow and fast subsystems. The matrices and are defined as follows, where is the dimension of , and is the nilpotency index of .
  • slow subsystem
    fast subsystem
  • The observability matrices only exist for descriptor systems in which Det[λ e-a]0 for some λ.
