State space analysis is an advanced method for the investigation of dynamic systems. It relies on the analysis of state variables that are usually vectors comprising a critical system variable, its derivative and optionally additional variables.

The state variable description of a system has the form

y = Hx + ju


x: State of the system (column vector, n elements for an nth order system)

F: n * n system matrix

G: n * 1 input matrix (column matrix)

H: 1 * n output matrix (row matrix)

j: direct transmission term

y: system output

u: system input
