Abstract We propose a distributed adaptive synchronous tracking control algorithm for the heterogeneous multi-unmanned surface vehicles described by Euler-Lagrange system. In system, inter-communication state can be represented directed topology graph, and only part of unmanned directly acquire accurate information time-varying reference trajectory. The proposed implement multiple without knowi...

The main purpose of this work is to present a robust speed control structure for two-mass system. tested system consists PI controller with two additional feedback. coefficients the are selected using pattern-search optimization method in order obtain robustness changes parameters. requires information about non-measurable state variables. For purpose, it proposed use multilayer observer. In sh...

In this paper, we introduce a new hyperchaotic complex T-system. This system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, Lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. We discuss the synchronization with certain and uncerta...

Uncertain inference is a process of deriving consequences from uncertain knowledge or evidences via the tool of conditional uncertain set. Based on uncertain inference, uncertain system is a function from its inputs to outputs. This paper proves that uncertain systems are universal approximators, which means that uncertain systems are capable of approximating any continuous function on a compac...
