In this paper we propose a concept for building simulation algorithms for switched fuzzy control systems. Using these concepts we have shown the whole process of modeling, stability analysis and design of stabilizing switched fuzzy logic controllers for the hovercraft-vehicle, as a typical nonholonomic system. Using this typical nonholonomic system (the… (More)

This article gives a brief overview of the basic notions of switched fuzzy systems, their model construction and stability analysis, followed by the proposed concepts for building simulation algorithms for this type of systems. Using these concepts we have shown the whole process of modelling, stability analysis and design of stabilizing switching fuzzy… (More)

Since early eighties, not too many happened in analytical methods of performance valuation for actual computer and communication networks. The methods of the classic queuing theory (the mean value analysis, the convolution method) adopt unrealistic assumptions. The stochastic queuing network methods are not adequate for investigation of actual networks.… (More)

This paper overviews recent advances in the field of switched fuzzy systems, switched systems whose subsystems are fuzzy systems, followed by the comparative study for this kind of systems. Starting with the basic ideas of switched fuzzy systems, the comparative study is aimed in introducing the diverse approaches in their model construction, as well as the… (More)

The problem of robust output feedback control for a class of uncertain switching fuzzy time-delay systems via common Lyapunov function and multiple Lyapunov function methods is solved. Based on employing Parallel Distributed Compensation strategy, the fuzzy output feedback controllers are designed such that the corresponding closed-loop system possesses… (More)

The present pa per discusses the problems of trusted software (including specialized operating systems) for the technology change and transfer in the domain of pioneering (emerging then) automation and ICT systems for the power industry in a rather not much developed case study country (Poland) and their basic solutions. The costs that had to be paid by the… (More)

Some novel results on a organizing supervisory control, employing fuzzy Petri-net reasoning, along with intelligent communication protocols tailored for flexible manufacturing systems are proposed. Stochastic Petri-net supervisor has been derived via a synergy of fuzzy set and Petri net theories while intelligent communication protocols via object oriented… (More)

Estimation of the domain of attraction of a class of susceptible infectious removed susceptible (SIRS) epidemic models for varying-size population with constant immigration is investigated. On assumption that the disease-free equilibrium and the endemic equilibrium exist, the domain of attraction of epidemic model is estimated by using sum-of-squares… (More)

From the very beginning of computer systems and networks, there has been a severe lack of analytical techniques enabling effective performance evaluation/prediction for actual systems and networks. Such techniques were needed, in particular, for the systems developed in rather poorly countries where the hardware available for the designers was obsolete in… (More)
