Multi-input, multi-output control system analysis and synthesis by singular value decomposition

Abstract

A systematic procedure has been developed for the synthesis of robust regulatory control systems comprising multi-input multi-output controllers. The technique is based on singular value decomposition and results in a simple matrix-proportional-plus-integral controller. An interactive computer-aided control system package has also been developed with the systematic technique incorporated. Two design examples are given to demonstrate the systematic nature of the design approach as well as the utility of its computer software.
