Background
- Multiagent systems (MASs) face challenges with heterogeneity, switching topologies, and denial-of-service (DoS) attacks.
- Existing containment control methods often struggle with fully heterogeneous MASs and uncertain system dynamics.
Purpose Of The Study
- To develop an adaptive resilient flexible output containment (FOC) control strategy for semi-Markov jump fully heterogeneous multiagent systems (FHMASs).
- To address challenges posed by random switching topologies, DoS attacks, and leader heterogeneity.
Main Methods
- Employed multiple asynchronous semi-Markov chains to model parameter variations and topology switching with uncertain transition rates (TRs).
- Developed a novel adaptive observer-based FOC control framework with adaptive gains for state observation.
- Designed a dynamic output feedback controller, decoupling containment coefficients from the Laplacian matrix.
- Utilized linear matrix inequalities (LMIs) to derive gain matrices under uncertain TRs.
Main Results
- Adaptive observers successfully estimated leader states despite unknown global topology and TRs, while resisting DoS attacks and topology switching.
- The dynamic output feedback controller achieved flexible output containment (FOC).
- Containment coefficients can be flexibly predefined, enhancing adaptability.
- LMIs provided a systematic way to obtain controller and estimator gains.
Conclusions
- The proposed adaptive resilient FOC control framework is effective for FHMASs under complex conditions.
- The method offers enhanced robustness against uncertainties and external attacks.
- The flexible FOC design broadens applicability in real-world scenarios.

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...
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:
V is the N-vector of bus voltages, E is the M-vector of machine voltages, I is...
Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
The principle of conservation of mass is fundamental in fluid dynamics and is crucial for analyzing flow within fixed control volumes, such as pipes or ducts. This principle states that the total mass within a control volume remains constant unless altered by the inflow or outflow of mass through the control surfaces. This results in a vital relationship for steady, incompressible flow where the mass entering a system equals the mass leaving it.
In the case of a sewer pipe, which can be modeled...
