Multivariable System Regulation

Abstract

Abstract

The regulation of multivariable systems which are subjected to input set point changes and disturbances is considered. A regulation strategy, for analysis purposes, employing both an inner- and an outer-loop feedback structure is proposed. Prescribed, closed-loop, dynamic behaviour using minimum control effort while confining steady-state output coupling is achieved. Output recovery, following disturbance perturbations, via proportional, outer-loop control is advocated. Elementary procedures enabling the computation of conventional pre and feedback compensators are provided, facilitating thereby cost-effective implementation. Stability assessment via established frequency domain techniques is acknowledged. Application studies, enabling comparisons with existing controller design methods, are outlined.
