When anlyaze a system in MATLAB/Simulink with linmod command,
we could achieve the matrices A, B, C, and D of linearized system equeation near operating point.
dx/dt=Ax+Bu
y=Cx+Du
But for more detailed anlysis,
the states that mapped with each columns and rows of A matrix are should be identified. but the command 'linmod' has no functions regarding the states of system.
how can we achieve the state information for the 'modal analysis??'
In order words, how can we achieve the information of state 'x'???
