Bifurcation Analysis, Synchronization and FPGA Implementation of a New 3-D Jerk System with a Stable Equilibrium

Abstract

This research paper addresses the modelling of a new 3-D chaotic jerk system with a stable equilibrium. Such chaotic systems are known to exhibit hidden attractors. After the modelling of the new jerk system, a detailed bifurcation analysis has been performed for the new chaotic jerk system with a stable equilibrium. It is shown that the new jerk system has multistability with coexisting attractors. Next, we apply backstepping control for the synchronization design of a pair of new jerk systems with a stable equilibrium taken as the master-slave chaotic systems. Lyapunov stability theory is used to establish the synchronization results for the new jerk system with a stable equilibrium. Finally, we show that the FPGA design of the new jerk system with a stable equilibrium can be implemented using the FPGA Zybo Z7-20 development board. The design of the new jerk system consists of multipliers, adders and subtractors. It is observed that the experimental attractors are in good agreement with simulation results.

The Reinartz Oscillator: Analysis Beyond Regular Behavior of the Circuit

“…After successful construction, obtained oscilloscope screenshots are compared with Matlab simulation outputs. Paper [36] demonstrate that only three building blocks are necessary to practically realize FPGA based 3D jerk systems, namely multipliers, adders and subtractors. Interesting feature of investigated systems is the presence of stable equilibrium, i.e., dynamics that exhibits hidden chaotic attractors.…”

A new four-dimensional hyperchaotic system with hidden attractors and multistablity

“…Chaos synchronization methods play a crucial role in chaotic secure communication. In recent years, researchers have actively explored various synchronization control methods, leading to rapid developments in the field of chaos synchronization [60][61][62]. In this section, we employ an active control approach to achieve synchronization between two identical novel hyperchaotic systems with different initial values.…”
