Event-Triggered Extended Dissipative FTB for T-S Fuzzy Switched Systems With Mismatched Phenomena and Deception...

Area of Science:

• Control Systems Engineering
• Fuzzy Logic Systems
• Networked Systems

Background:

• Fuzzy switched systems are susceptible to deception attacks, compromising their stability.
• Existing event-triggered mechanisms often struggle with network resource efficiency and mode mismatches.

Purpose of the Study:

• To investigate the extended dissipative finite-time boundedness (ED-FTB) for fuzzy switched systems under deception attacks.
• To propose a multidomain probabilistic event-triggered mechanism (MDPETM) for improved network resource efficiency.
• To address mode mismatch issues between controllers and systems.

Main Methods:

• Modeling mode mismatch using switching delay information.
• Developing a virtual delay concept to extract true signals from the MDPETM.
• Designing mismatched fuzzy state feedback controllers.
• Establishing fuzzy basis and controller mode-dependent Lyapunov functionals.

Main Results:

• Sufficient criteria for ED-FTB were derived, free of nonlinear terms.
• The proposed MDPETM enhances network resource efficiency.
• The controller and system premise variables are no longer constrained to be identical.
• Theoretical results were validated on a one-link robotic arm system.

Conclusions:

• The developed framework effectively ensures ED-FTB for fuzzy switched systems under deception attacks and delays.
• The MDPETM offers a practical approach to managing network resources in event-triggered control systems.
• The removal of the same premise variable constraint broadens the applicability of fuzzy control design.
