Finite-time consensus for multi-agent systems (MAS) with high-order nonlinear uncertain dynamics under directed communication topology is still an open problem due to the involvement of high-order nonlinear uncertain dynamics; one-way directed communication constraints; and unknown time-varying control effectiveness gain. In this paper, based upon the locally defined consensus error and fractio...

One of the most challenging issues in adaptive control robot manipulators with kinematic uncertainties is requirement inverse Jacobian matrix regressor form. This inevitable case parallel robots, whose dynamic equations are written directly task space. In this paper, an controller designed for robots based on representation form, such that asymptotic trajectory tracking ensured. The main idea s...

Opinion formation describes the dynamics of opinions in a group of interaction agents and is a powerful tool for predicting the evolution and di usion of the opinions. The existing opinion formation studies assume that the agents express their opinions by using the exact number, i.e., the exact opinions. However, when people express their opinions, sentiments, and support emotions regarding di ...

In this survey we report some recent results in the mathematical modelling of epidemic phenomena through use kinetic equations. We initially consider models interaction between agents which social characteristics play a key role spread an epidemic, such as age individuals, number contacts, and their economic wealth. Subsequently, for models, discuss possibility containing appropriate optimal co...

In the environment of business‐to‐business e‐commerce, Buyers and sellers in mature industrial markets can turn single transactions into long-term beneficial relationships by a deeper understanding of the complex connection between the two and buyers and sellers are uncertain about their roles. A “must-do” for the sellers, in particular, is to understand patterns of investment and reward,...
