Modified model of unified chaotic system and the design of synchronization

A new simplified three-dimensional piecewise continuous autonomous system(a modified model of unified chaotic system) was introduced by replacing a quadratic nonlinear term in a unified chaotic system with a piecewise linear signum function.The qualitative properties of this modified model were studied to substantiate that it is a chaotic system.Two kinds of nonlinear controllers were designed to theoretically synchronize two uncertain modified models of unified chaotic system.Numerical simulations were presented to show the effectiveness of the methods.
