Special Issue Information

Dear Colleagues,

Many realistic systems can be modeled using dynamical equations. Increasing system performance requirements need to deal with the increasingly complicated dynamical systems used to simulate reality in control system analysis and design. Nonlinearity, uncertainty, time delay, system singularity, stochastic effects, the presence of linkages, and other factors contribute to the complexity. Technological and control theory advancements have made it possible to analyze complicated dynamical systems. Complex systems research is becoming increasingly essential, providing an additional push for the development of novel approaches and abilities for complex control systems. It has been applied widely in many complex fields, for example in missile guidance systems, active vehicle suspension systems, automobile control systems, etc. Due to their theoretical and practical significance, complex dynamical systems have long been and will continue to be one of the most active research areas. Although there have been many interesting publications on complex dynamical systems in recent years, there remain many challenging open issues. This provides the motivation for this Special Issue.

One of the main goals of this Special Issue is to bring together the latest innovative knowledge, analysis, and modeling techniques of control problems in dynamical networks. We accept both original research and review articles, and papers must contain unique theory or design material. The Special Issue focuses on recent achievements and applications in the field of complex system control and analysis, with particular emphasis on how to solve various control and observer design problems for nonlinear and interconnected systems. The systems under consideration typically have at least two functions: nonlinearity, faults, time delays, disturbance/uncertainty, interconnections between subsystems, stochastic processes, system singularities, and comparisons between simulations and experiments. The Special Issue focuses on the results of theoretical research and practical applications, with a focus on new methodologies for analysis, design, synthesis, and/or applications. Interconnected/networked systems, variable structure control, singular system control, time delay systems, fuzzy control and impulsive control, robust observer design and parameter identification, fault detection and fault-tolerant control, analysis and control of stochastic systems, and applications of advanced control systems are among the topics covered in this Special Issue.

Global quadratic stability and L2 performance in probability (quadratic stability and L2 gain γ in probability: abbreviated as GQL2(γ)-P) is studied for switched systems consisting of linear stochastic subsystems with norm-bounded uncertainties. Under the assumption that there is no single subsystem achieving GQL2(γ)-P, it is shown that if there exists a convex combination of subsystems achieving GQL2(γ)-P, then a state-dependent switching law, based on the convex combination of subsystems, is proposed under which the switched system achieves GQL2(γ)-P. Then, the discussion is extended to the case involving state feedback controller gain. A numerical example and the application to DC–DC boost converters are provided to demonstrate the proposed design condition and the algorithm. Full article

In this paper, we propose and derive a new system called pure hybrid fuzzy neutral delay differential equations. We apply the classical fourth-order Runge–Kutta method (RK-4) to solve the proposed system of ordinary differential equations. First, we define the RK-4 method for hybrid fuzzy neutral delay differential equations and then establish the efficiency of this method by utilizing it to solve a particular type of fuzzy neutral delay differential equation. We provide a numerical example to verify the theoretical results. In addition, we compare the RK-4 and Euler solutions with the exact solutions. An error analysis is conducted to assess how much deviation from exactness is found in the two numerical methods. We arrive at the same conclusion for our hybrid fuzzy neutral delay differential system since the RK-4 method outperforms the classical Euler method. Full article
