Lag synchronization and simulation by Simulink ofnew four dimensional hyperchaotic system
一个新的四维超混沌系统的滞后同步及其Simulink仿真

This paper investigated lag synchronization and parameter identification of a new four dimensional hyperchaotic system. Based on Lyapunov stability theory and adaptive control method, it designed the controller using the state error feedback, realized lag synchronization of the hyperchaotic system and identified all the unknown parameters, and also confirmed the control gains of the controller with or without noise. It used numerical simulation based on Simulink to verify the effectiveness, feasibility and robustness of the theory.
