Decentralized Impulsive Control for Nonlinear Interconnected Systems Based on Dynamic Event-Triggered Mechanism
IEEE Transactions on Cybernetics
|January 19, 2026
Summary
This study introduces a novel dynamic event-triggered impulsive control for nonlinear interconnected systems. The method ensures system stability and performance by applying control only at specific moments, reducing computational load.
Area of Science:
- Control Systems Engineering
- Nonlinear Dynamics
- Artificial Intelligence
Background:
- Decentralized control is crucial for complex nonlinear interconnected systems (NISs).
- Traditional event-triggered control (ETC) can still incur significant communication and computation overhead.
- Impulsive control offers potential for reduced control effort by acting only at discrete instants.
Purpose of the Study:
- To develop a decentralized impulsive control strategy for NISs using a dynamic event-triggered mechanism.
- To design a fuzzy logic system (FLS)-based backstepping controller for impulsive control.
- To ensure prescribed performance constraints and stability in closed-loop systems.
Main Methods:
- A fuzzy logic system (FLS)-based backstepping approach was used to design the impulsive controller.
- A dynamic event-triggered mechanism was employed to determine impulse instants.
- Lyapunov stability analysis was utilized to prove system boundedness and performance achievement.
- The approach was extended to an output-feedback scenario using observer states.
Main Results:
- A novel dynamic event-triggered impulsive controller was proposed for NISs.
- The closed-loop impulsive systems demonstrated hybrid dynamics, nonlinear characteristics, and prescribed performance.
- Lyapunov analysis confirmed that all closed-loop states remain bounded.
- Prescribed tracking performance was achieved, with tracking errors converging to a bounded region in finite time.
- The impulsive control scheme was successfully extended to the output-feedback case.
Conclusions:
- The proposed dynamic event-triggered impulsive control scheme effectively manages nonlinear interconnected systems.
- The FLS-based backstepping approach ensures stability and achieves prescribed performance with reduced control actions.
- The method offers a viable solution for decentralized control problems with hybrid dynamics and performance constraints.

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
