In order to promote the application of simple structure chaotic system in engineering,a new four-dimensional chaotic system with only one quadratic nonlinear term was proposed.For the proposed new system,firstly,the dynamic properties of the system were analyzed theoretically,and then the attractor diagram and Lyapunov exponent diagram of the new system were drawn by MATLAB.The simulation resulted verify the chaotic characteristics of the system.After that,the state observer was chosen to design the synchronization of the new chaotic system.Through the numerical simulation of MATLAB software,the generated error image was observed and the good experimental results were obtained,which also proveed the feasibility of the synchronization method.
