This paper presents a new hyperchaotic system which shows some interesting features, the system is 4-dimensionala with 4 nonlinearities. An extensive numerical analysis has showed that the system has some interesting features and strange behaviours. The numerical analysis includes studying the effect of system parameters and initial conditions. Some of the important properties of the system with parameter set, in which the system is hyperchaotic, such as Lyapunov exponents and Lyapunov dimension, dissipation and symmetry are found and discussed. In the next part of our work, a tracking controller for the proposed system is designed and then a synchronization control system for two identical systems is designed. The design procedure uses combination of a simple synergetic control with adaptive updating laws to identify the unknown parameters derived basing on Lyapunov theorem. Hardware implementation based on microcontroller unit (MCU) board is proposed and tested and used to experimentally validate the designed control and synchronization systems. As an application, the designed synchronization system is used as a secure analogue communication system. Using Matlab, Simulation study for the control and synchronization systems is presented. The simulation and experimental study have been showed excellent results.
