Special Issue Information

Dear Colleagues,

In the context of complex dynamic system modeling, identification, and control, the concept of entropy can play a significant role, particularly in understanding system behavior and dynamics, such as quantifying uncertainty or information content and selecting models by evaluating their predictive capacity and complexity, linking to robustness in control systems, where maintaining a certain level of entropy can help avoid predictable failures or limit cycle behaviors.

Integrating entropy into complex dynamic system modeling, identification, and control can enhance the understanding of system dynamics, improve data-driven decision making, and support the development of robust control strategies. This Special Issue presents new and improved insight, methodologies, and MIC techniques for complex systems that are challenging for research and (potentially) significant for a wide range of applications in real-world natural and engineering domains. Fundamentally, the papers should justify why the works have not been undertaken by the other colleagues and what the bottleneck issues have been the barriers for such research progression and applications. With academic rigorousness, this Special Issue is encouraging those emerging insights and approaches to provide concise/effective solutions in dealing with complex dynamic systems. The philosophy embedded in the S.I. is to seek simplicity (solutions) from complicity (problems). The editors look forward to receiving high-quality submissions and fostering interdisciplinary discussions to address the complex challenges appearing in these systems. Topics of interest include, but are not limited to, the following:

  • Adaptive and intelligent approaches;
  • Model-free, data-driven systems;
  • Robustness-augmented concepts and methodologies;
  • Complex system computational algorithms and interpretability;
  • Simulink configurated experimental platforms;
  • Emerging application-oriented methodologies and technologies;
  • Challenging applications in robotics and autonomous systems, thermodynamic systems, general underactuated control systems, time-delayed processes, etc.;
  • Authoritative survey in related domains.

Abstract
In this paper, the solutions of a class of switch dynamical systems are investigated. The right-hand side of the underlying equations is discontinuous with respect to the state variable. The discontinuity is represented by jump discontinuous functions such as signum or Heaviside functions. [...] Read more.
In this paper, the solutions of a class of switch dynamical systems are investigated. The right-hand side of the underlying equations is discontinuous with respect to the state variable. The discontinuity is represented by jump discontinuous functions such as signum or Heaviside functions. In this paper, a novel approach of the solutions of this class of discontinuous equations is presented. The initial value problem is restated as a differential inclusion via Filippov’s regularization, after which, via the approximate selection results, the differential inclusion is transformed into a continuous, single-valued differential equation. Besides its existence, a sufficient uniqueness condition, the strengthened one-sided Lipschitz Condition, is also introduced. The important issue of the numerical integration of this class of equations is addressed, emphasizing by examples the errors that could appear if the discontinuity problem is neglected. The example of a mechanical system, a preloaded compliance system, is considered along with other examples. Full article

Active noise control (ANC) technology has extensive applications in suppressing sound pollution in the real-world environment. In this paper, a new adaptive neuro-fuzzy network (ANFN)-based controller is presented and integrated into hybrid active noise control (HANC) systems to improve the robustness and effectiveness of active noise suppression. Specifically, an adaptive neural network is constructed to minimize the mean square error information with respect to the residual noise. Moreover, a fuzzy logic strategy is proposed to address the manual fine-tuning and nonlinearities encountered in a complex environment. Finally, the stability of the proposed control method is proved by using the Lyapunov theorem. Comparative numerical simulations are given to verify the effectiveness and superiority of the proposed method under different noise signals. Full article
