摘要:

A new interpretation and solution of the linear multivariate steady-state tracking and disturbance rejection problem is presented. On condition of reference and disturbance input variables with constant final values the proposed method prepares the ground for the calculation of a constant feedback control law, which meets the steady-state requirements exactly, although doing without the conventional prefilter or integral feedback respectively. Nevertheless the practical design reduces to the standard problem of stabilizing a precontrolled system by fictitious constant output feedback. The method is illustrated by the examples of a fourth-order nuclear rocket engine and a twelfth-order chemical absorption column.
