Special Issue Information

Dear Colleague,

In dynamical systems and control theory, convergence plays a fundamental role in understanding and manipulating complex nonlinear systems. Nonlinear systems are ubiquitous in nature and engineering, so their convergence analysis is crucial. This Special Issue delves into the convergence of nonlinear systems, shedding light on its significance and applications.

Achieving convergence is a critical objective in control theory. Control algorithms aim to guide a system towards a desired state, and ensuring convergence ensures that the system settles into the desired configuration accurately and efficiently. For instance, in autonomous vehicle control, convergence guarantees that the vehicle's trajectory converges to the desired path, enhancing safety and precision. In dynamical systems, convergence analysis helps in understanding the long-term behavior of systems. Chaos theory, for example, explores the behavior of chaotic systems and examines whether they strongly depend on initial conditions or eventually converge to certain attractors. Understanding convergence properties in chaos theory is vital for predicting and controlling chaotic systems, such as weather patterns or financial markets.

In conclusion, the convergence of nonlinear systems is a fundamental concept in dynamical systems and control theory. It underpins the stability and predictability of complex systems, facilitating their control and manipulation. Researchers and engineers continue to explore and develop sophisticated techniques to ensure convergence, enabling advancements in various fields and technologies.

We consider a two-group social conflict under the corporates’ research and development (R&D) business processes. Conflict participants are divided into two groups depending on their attitude to new ideas, technologies, and behavioral style for R&D creative problems—innovators and adapters. We reveal the contradiction that arises between the need to include both types of employees in one project team and their objectively antagonistic positions regarding the methods and approaches to R&D processes. The proposed research methodology is based on a modern post-non-classical paradigm formed on the principles of coherence, interdisciplinarity, openness, and nonlinearity, as well as a sociophysical approach to the social conflicts modeling. We use the general theories of magnetism, paramagnetism, and functions of P. Langevin and L. Brillouin to describe the dynamics of group participants’ preferences regarding the style of conflict behavior. The analogy of paramagnetism, consisting in the orienting effect of the magnetic field, is used to describe social groups interactions that have not only their own interests, but are also influenced by the opinions of opposite social groups. A two-dimensional, four-parameter map represents the dynamics of group conflict. Modeling results show that regardless of the initial states and with certain parameters of intra-group and intergroup interactions, the trajectories eventually converge to an attractor (limit cycle) in a two-dimensional space. No non-periodic or chaotic modes are identified in the two-group conflict, which determines the controllability of the described conflict. The results of the simulation experiments are used as decision support and contradictions resolution aimed at forming the required modes of the corporates’ research and development business processes and ensuring the group participants’ cohesion and depolarization. The results of testing the model at an industrial enterprise are presented. Full article
