摘要：Spherical tank systems are characterized by high uncertainty which makes hard to maintain its good stability margins and performance for closed loop system [7]. In conventional control, if the system parameter changes we cannot guarantee about the system performance hence it is important to design robust control for uncertain plant. In this paper the Quantitative Feedback Theory (QFT) has proved its dominance especially in the case of significant parametric uncertainty. The feature of Quantitative Feedback Theory is that it can take attention of huge parametric uncertainty along with phase information. For the purpose of QFT, the feedback system is usuallydefined by the twodegrees of freedom arrangement. Here in the Spherical tank system the height can be controlled by manipulating the feed Inflow rate of the system.
