Abstract：In order to generate chaotic dynamic behavior, aiming at a class of chaotic system, the chaos anti control method is improved, and the symmetrical piecewise linear state feedback controller is designed. The chaos of the linear system can be controlled by adjusting the parameters of the controller. The chaos is proved by combining the maximum Lyapunov index. The stability of the equilibrium point is analyzed according to the Routh Hurwitz criterion, and the dynamic behavior of the chaotic system is analyzed in detail. The new system is used to encrypt the image. The simulation results show that the histogram distribution is uniform and the correlation between adjacent pixels is small. It shows that the designed chaos system has high security performance in image encryption system.
