Abstract :
This paper considers the robust stability of non-sequential (NS) MIMO quantitative feedback theory (QFT) designed control systems. The sufficient conditions for robust closed-loop stability proposed in Zhao and Jayasuriya (1996) are examined and a less conservative sensitivity condition is formulated. The sufficient conditions proposed herein apply to the class of systems covered by the NS MTMO QFT design method presented in Horowitz (1979).
