The Analysis and Circuit Implementation of a New Hyper-Chaos System

This paper simply analyses a hyper-chaos system which based on the modified Lorenz system, and chiefly designs its circuit. In this paper, the different phase portraits of the system are studied when the system parameter k is varied. The circuit of the system is implemented by the operational amplifiers and the analog multiplier, it includes four channels. Some phase portraits can be observed through analog oscillation when adjusting corresponding resistor. The result from the circuit is approximately same as that from computer simulation.
