Abstract: A control system design based on the T-S fuzzy model with uncertainty is considered in this paper. At first, state observer is developed to estimate the state properly despite the existence of the uncertainty. Then, uncertainty observer is derived using the estimated state. Finally, a controller based on the observers is proposed in an effort to counteract the influence of the uncertainty whatever possible. In addition, the Nussbaum-type function and its relevant properties are used in the controller design to cover the observers’ error and the part of estimated uncertainty that is not possibly used through the control matrices. As a result, the closed-loop control system becomes asymptotically stable.
