Event-based multirate control of large-scale distributed nonlinear systems subject to time-driven zero order holds

摘要: Abstract The event-based output-feedback control is studied for large-scale distributed networked nonlinear systems. All subsystems are described by interval type-2 (IT2) Takagi–Sugeno (T–S) model and communicate information to each other via networks with time-varying transmission delays. sampled rates of sensors refresh actuators allowed be different among subsystems. We propose an scheme in the sense that subsystem determines its based on local output measurements. First, combined descriptor system perturbed approaches, equivalent transformation established. Then, a relaxing Lyapunov functional introduced virtue Wirtinger inequality. corresponding co-design criteria obtained form linear matrix inequalities (LMIs), which guarantee stabilization closed-loop fuzzy sampling updating while transmitting as little possible. Furthermore, employing some bounding inequality techniques, considerable reduction number LMIs can achieved. Finally, practical application DC microgrid three PV exploited.
