- Abstract
This study presents the robust H∞ control of polynomial fuzzy systems when model uncertainties and external disturbances are simultaneously taken into account. Using a non‐quadratic Lyapunov function, two stability conditions were derived in the form of sum‐of‐squares (SOS). The proposed polynomial fuzzy controller possesses H∞ robust performance against norm‐bounded disturbances and uncertainties. Simulation results demonstrated the effectiveness of the proposed SOS‐based stability conditions, which are more general than those of existing approaches.
