| Abstract: | This paper is devoted to the composite hierarchical anti-disturbance fuzzy control for nonlinear interconnected systems (NISs) subject to multiple disturbances, including a norm-bounded disturbance and an unknown disturbance generated by an exogenous system. H∞ control and the composite disturbance-observer-based control consisting of a feedforward compensation term and a state-feedback sampled-data control are employed to attenuate and compensate these two types of disturbances in the T-S fuzzy framework, respectively. To start with, NISs, exogenous disturbance, disturbance observer, and composite controller are all modeled using T-S fuzzy model technology. By building a time-dependent function, a sufficient condition is then established to ensure the exponential stability of the estimation error system and closed-loop NISs with a prescribed H∞ performance level. Following this, the joint design of the desired observer and composite disturbance-observer-based fuzzy controller is developed. Finally, a numerical simulation is performed to demonstrate the effectiveness of the presented composite hierarchical control scheme. [ABSTRACT FROM AUTHOR] |
