A Decentralized Event-Triggered Dissipative Control Scheme for Systems With Multiple Sensors to Sample the System Outputs

Area of Science:

• Control Systems Engineering
• Networked Systems

Background:

• Decentralized control systems often face challenges with communication constraints.
• Systems with outputs of varying physical properties require specialized control strategies.

Purpose of the Study:

• To develop a decentralized event-triggered dissipative control method for systems with multi-property outputs.
• To enhance communication efficiency while maintaining system performance.

Main Methods:

• Grouping system outputs into nodes based on physical properties.
• Implementing a decentralized event-triggering scheme with a data packet processor (DPP).
• Modeling the closed-loop system as a linear system with interval time-varying delay.

Main Results:

• A sufficient condition for asymptotic stability and strict (Q0,S0,R0)-dissipativity is derived.
• The proposed method significantly saves communication resources.
• Output-based controllers are designed using linear matrix inequalities.

Conclusions:

• The proposed decentralized event-triggered dissipative control is effective for systems with diverse output properties.
• The method offers a viable approach to conserve communication bandwidth without compromising stability and performance.
