In this paper, a novel approach is proposed for generating fractional-order multiwing chaotic attractors. Based on a fractional-order linear differential system, by introducing the nonlinear state feedback controller equipped with an even symmetric multisegment quadratic function, various fractional-order multiwing chaotic attractors can be generated. An(More)
This paper initiates a novel approach for generating multi-wing butterfly chaotic attractors from the piecewise-linear Chen system by constructing a duality-symmetric multi-piecewise linear function. It should be pointed out that this proposed method is different from the traditional techniques. Furthermore, its dynamical behaviors are then further(More)
This paper has constructed a new multi-scroll chaotic system. Two-scroll chaotic attractor can be generated from a basic linear system by switching control in one direction. Then grid multi-scroll chaotic attractors can also be attained by controlling in two directions. The designed two-scroll system and multi-scroll system are chaotic in the sense of Smale(More)
In this paper, a fractional-order multi-wing chaotic attractors evolved from Lü system is proposed. Based on the theory of fractional calculus, fractional-order multi-wing chaotic attractors are simulated, and its dynamical characteristics are also given. Numerical simulation reveals that multi-wing chaotic attractors can be generated in Lü(More)
In this paper, based on LaSalle's invariance principle and linear matrix inequality (LMI), two novel synchronization criteria for the unified chaotic systems with known or unknown parameters are investigated. In comparison with previous methods, the presented controller contains single state feedback. To our knowledge, the above control scheme is the(More)
