This file discribes a structure for stabilization and tracking between two identical hyperchaotic lu systems with different initial conditions and nonlinear control input. On the basis of Lyapounov theory, a first order sliding mode controller is designed for global asymptotically stabilization and tracking, so error dynamics between hyperchaotic lu master and slave system satisfy by input nonlinear control signal. Then a second order sliding mode controller by using super-twisting algorithm is designed. In this file, results of simulation shows the rate of effectiveness from this suggested method.

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.
