Abstract

This paper presents an improved non-sequential MIMO QFT design method for uncertain systems. The paper considers the robust stability of non-sequential MIMO QFT designed closed-loop control systems. A non-sequential MIMO QFT stability theorem is derived that serves as the basis for an improvement of the design methodology, whereby it can be successfully applied to non-minimum phase systems, albeit with a degree of conservatism partially inherent in independent and decentralised design methodologies. The results improve the non-sequential MIMO QFT design methodology and provide insight into the plant cases for which the methodology can be successfully applied.
