چکیده
In this paper, a new 2-dimensional chaotic map with simple algebraic form is proposed. And the numerical solution of corresponding fractional-order derived. It novel that still exhibits behaviors when expanded to and improper fractional-order. The dynamical characteristics these three forms are detected through bifurcation diagram, maximum Lyapunov exponent spectrum, Kolmogorov entropy attractor portraits. More interestingly, has multiple coexisting attractors, but multistability more complicated than integer-order form. addition, Permutation (PE) complexity algorithm diagram used explore dynamic changes amplitude simultaneously. analysis shows under appropriate order, range larger integer order. This research provides guidance on application teaching discrete systems.

Integer-order Versus Fractional-order Adaptive Fuzzy Control of Electrically Driven Robots with Elastic Joints
Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...
متن کاملRobust stabilization of a class of three-dimensional uncertain fractional-order non-autonomous systems
This paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. In this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. The robust controller is designed on the basis of fractional Lyapunov stability theory. Furthermore, the effects of model uncertai...
متن کاملDesign of Fractional-Order PI Controller For Integer-Order Systems
The aim of this work is to design a fractional-Order PI controller for Integer-order type systems so that to improve the performance and robustness of integer-order type systems. The design of FO-PI controller in the sense that good set-point tracking and load disturbance rejection is minimized by increasing fractional-order element “α” putting constraint on peak sensitivity function. The metho...
متن کاملStudy on stability analysis of distributed order fractional differential equations with a new approach
The study of the stability of differential equations without its explicit solution is of particular importance. There are different definitions concerning the stability of the differential equations system, here we will use the definition of the concept of Lyapunov. In this paper, first we investigate stability analysis of distributed order fractional differential equations by using the asympto...
متن کاملThe Two Forms of Fractional Relaxation of Distributed Order
The first-order differential equation of exponential relaxation can be generalized by using either the fractional derivative in the Riemann–Liouville (R-L) sense and in the Caputo (C) sense, both of a single order less than 1. The two forms turn out to be equivalent. When, however, we use fractional derivatives of distributed order (between zero and 1), the equivalence is lost, in particular on...
