This paper studies the practical exponential stability of an impulsive stochastic food chain system with time-varying delays (ISOFCSs). By constructing auxiliary equivalent to original and comparison theorem, existence global positive solutions suggested is discussed. Moreover, we investigate sufficient conditions for system, which given by Razumikhin technique Lyapunov method. In addition, whe...

In this paper, we investigate the partial practical exponential stability of neutral stochastic functional differential equations with Markovian switching. The main tool used to prove results is Lyapunov method. We analyze an illustrative example show applicability and interest results.

The article considers the basic scientific approaches to economic contents of notions financial stability, mechanism enterprise management. Offered interpretations concept stability management and main stages process its formation. activity Ukrainian "Stalkonstruktsia" LLC is characterized. It was determined that during 2019-2021, company's balance sheet completely liquid, which indicates a suf...

In this study, the concept of the chemical substance pheromone is utilized for the robotic tasks. This paper first illustrates the model of pheromone-based potential field. The field is constructed through the interaction between mobile robots and data carriers, such as RFID tags. The emphasis in the modeling of the system is on the possibility of the practical implementable ideas. The stabilit...

In this paper, a Robust adaptive neural network controller (RANNC) based on variable structure system for robotic manipulators is proposed to alleviate the problems met in practical implementation using classical variable structure controllers. The chattering phenomenon is eliminated by substituting single-input single-output radialbasis-function neural networks (RBFNN's), which are nonlinear a...
