Append state vector to output vector
asys = augstate(sys)
asys = augstate(sys) appends the state
vector to the outputs of a state-space model.
Given a state-space model
sys with equations
(or their discrete-time counterpart),
the states x to the outputs y to
form the model
This command prepares the plant so that you can use the
to close the loop on a full-state feedback u =
augstate is only meaningful for state-space
models, it cannot be used with TF, ZPK or FRD models.
