Hierarchical anti-disturbance Control for Semi-Markovian Jump T-S Fuzzy Systems with nonlinearity via multiple disturbances

摘要

This paper addresses a method of hierarchical disturbance-observer-based control (DOBC) and ℋ_∞ control for Semi-Markovian jump T-S fuzzy systems with nonlinearity and multiple disturbances. The focus is on designing a disturbance observer to estimate the disturbance. And then design a control strategy by combining the output of the disturbance observer with the state feedback gain to guarantee the considered closed-loop system is stochastically stable. Based on Lyapunov theory, linear matrix inequalities (LMIs) conditions are constructed.
