This letter discusses hybrid projective dislocated synchronization of Liu chaotic system with five uncertain parameters. Based on adaptive technique, the hybrid projective dislocated synchronization of Liu chaotic system is achieved by designing a novel nonlinear controller. Furthermore, the parameters identification is realized simultaneously. A sufficient condition is given and proved theoret...

In this paper we present a method of hybrid predictive control (HPC) based on a fuzzy model. The identification methodology for a nonlinear system with discrete state-space variables based on combining fuzzy clustering and principal component analysis is proposed. The fuzzy model is used for HPC design, where the optimization problem is solved by the use of genetic algorithms (GAs). An illustra...

Border collision bifurcations refer to situations where a small parameter variation induces a change in the event sequence of a hybrid system. At such a bifurcation, the system trajectory makes tangential contact with an event triggering hypersurface. This bounding case separates regions of (generally) quite different dynamic behaviour. In the paper, the conditions governing bifurcation points ...

This paper address a novel method for nonholonomic Wheeled Mobile Robot (NWMR) trajectory tracking using a hybrid controller. In the essential of the proposed scheme, hybrid algorithm includes fuzzy logic based Regulation, Pole-Placement and Tracking (F-RST). The hybrid controller easily track the reference trajectory and linearize the nonlinear behavior of robot under the influence of uncertai...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

We study both theoretically and experimentally the nonlinear interaction between an intense surface acoustic wave and a two-dimensional electron plasma in semiconductor-piezocrystal hybrid structures. The experiments on hybrid systems exhibit strongly nonlinear acoustoelectric effects. The plasma turns into moving electron stripes, the acoustoelectric current reaches its maximum, and the sound ...

Abstract With the motivation of avoiding the computation of the inverse of Jacobian matrix, which is involved in Newton’s method, we consider the use of vector divisions in solving a nonlinear system of equations F (x) = 0. Vector divisions are applied to form the secant method formulas. Based on that, a globally convergent hybrid algorithm for solving the nonlinear system of equations is propo...

In this paper, we develop an algorithm to compute underand over-approximations to the discrete dynamics of a hybrid automaton. We represent the approximations to the dynamics as sofic shifts, which can be generated by a discrete automaton. We restrict to two-dimensional systems, since these give rise to one-dimensional return maps, which are significantly easier to study. Given generic non-dege...

In this paper, hybrid impedancehime-delay control is used for a robot to successfully achieve contact tasks without changing a control algorithm or controller gains throughout all three modes: free space, contact transition and constrained motion. In order to absorb impact forces and stabilize the system upon collision with a stiff environment, a nonlinear bang-bang impact controller is develop...
