Its dynamical analyses, circuit experiment, control and synchronization applications are presented. Design/methodology/approach A new 4D hyperchaotic attractor is achieved through a simulation, circuit experiment and mathematical analysis by obtaining the Lyapunov exponent spectrum, equilibrium, bifurcation, Poincaré maps and power spectrum. Moreover, hardware experimental measurements are performed and obtained results well validate the numerical simulations. Also, the passive control method is presented to make the new 4D hyperchaotic system stable at the zero equilibrium and synchronize the two identical new 4D hyperchaotic system with different initial conditions. Findings The passive controllers can stabilize the new 4D chaotic system around equilibrium point and provide the synchro...

In addition, the bifurcation analysis of the system is studied with respect to a certain parameter. The electronic circuit implementation of a chaotic system is realized and compared with the phase portraits obtained from Matlab and circuit realization. Also, passive control technique is applied to stabilize and suppress the chaos in the chaotic system. Numerical simulations are presented to verify the theoretical analysis and the effectiveness of the proposed control method.
