This article presents the $L_1$ -gain polynomial fuzzy output-feedback controller design and stability analysis using sum-of-squares (SOS) approach for positive fuzzy-model-based (PPFMB) control systems. The polynomials, positivity, opt...

Assisting humans in collaborative tasks is a promising application for robots, however effective assistance remains challenging. In this paper, we propose method providing intuitive robotic based on learning from human natural limb coordination. To encode coupling between multiple-limb motions, use novel interval type-2 (IT2) polynomial fuzzy inference modeling trajectory adaptation. The associ...

This study addresses the issue of robust dynamic output feedback control (DOF) for polynomial Takagi–Sugeno (T–S) fuzzy systems in Finite Frequency (FF) domain. Sufficient conditions designing DOF are derived terms sum squares (SOS). The proposed strategy is built FF domain to reduce conservation-generated by techniques established whole frequency In addition, there no transformation matrices o...

This paper presents a descriptor representation-based guaranteed cost design methodology for polynomial fuzzy systems. applies the representation presenting closed-loop system of model with parallel distributed compensation (PDC) based controller. By utility representation, control (GCC) analysis can utilize slack matrices obtaining less conservative results. The proposed GCC is presented as su...
