Design of Polynomial-Fuzzy-Model-Based Networked Control Systems:Sum of Squares Approach

【摘要】：正This paper is concerned with the problem of control of polynomial-fuzzy-model-based systems by using sum of square (SOS) approach in the network environment,where both network-induced delay and packet dropout are addressed.Based on the Lyapunov-Krasovskii stability theory and Finsler's lemma,the stability analysis and controller design conditions are obtained. These conditions generalize previous results that were derived using linear-matrix-inequality(LMI) approach.Moreover,a generalized results can be obtianed by bringing the membership functions as polynomial variables for relaxation of SOS-based stability conditions,which can be numerically solved by using the SOSTOOLS.
