Despite that endoscopic retrograde cholangiopancreatography(ERCP) has become the gold standard in the treatment of benign biliary obstruction, bilioenteric anastomosis still represents a valid option to treat the increasing number of patients with recalcitrant obstruction, and/or altered anatomy after digestive surgery [1,2]. Minimally invasive techniques have become the standard of care for the surgery of the biliary tract in specialized centers [2,3].

Optimal guaranteed cost control for an uncertain discrete T-S fuzzy system with time-delay

引用

控制理论与应用（英文版） 2009年第2期7卷 144-150页

作者： Renming WANG Thierry Marie guerra Juntao PAN College of Electrical Engineering and Information Technology Three Gorges University Yichang Hubei 443002 China LAMIH UMR CNRS Universite de Valenciennes et du Hainaut-Canbresis Le Mont Houy Valenciennes Cedex France Key Laboratory of Measurement and Control of CSE of Ministry of Education Southeast University Nanjing Jiangsu 210096 China

This paper considers the guaranteed cost control problem for a class of uncertain discrete T-S fuzzy systems with time delay and a given quadratic cost function. Sufficient conditions for the existence of such controllers are derived based on the linear matrix inequalities （LMI） approach by constructing a specific nonquadratic Lyapunov-Krasovskii functional and a nonlinear PDC-like control law. A convex optimization problem is also formulated to select the optimal guaranteed cost controller that minimizes the upper bound of the closed-loop cost function. Finally, numerical examples are presented to demonstrate the effectiveness of the proposed approaches.
