Robust H-infinity control of nonlinear networked systems with uncertainty
|
Abstract:
The robust control for nonlinear networked systems with parameter uncertainties by the T-S(Takagi-Sugeno) fuzzy approach is investigated. Firstly, with consideration of the effect of network conditions, such as network-induced delays and data packet dropouts, we develop a sampled-data model for the closed-loop feedback system based on the updating sequence of the event-driven holder. This model is converted to a continuous T-S fuzzy system with two additivedelay components in the states. Next, by using the delay system approach, the robust H-infinity performance for the uncertain closed-loop fuzzy system is analyzed, and the robust H-infinity fuzzy controller is designed. Finally, a simulation example is provided to illustrate the effectiveness of method.
