Abstract

Recently, the introduction of high-dimensional systems with a larger Lyapunov exponent is very difficult
and more complex. The paper introduces a new four-dimensional hyperchaotic system with a larger Lyapunov exponent
compared with 20 works available in literature. Th proposed system will be derived from the Lorenz-like system via a state
feedback control approach and consist of eight terms only. This system lacks equilibrium points but can generate hidden
attractors. Two positive Lyapunov exponents (LE) indicating hyperchaotic behavior have been identified. The
mathematical properties of this dissipative hyperchaotic system are both theoretically and numerically presented,
encompassing Lyapunov exponents, Lyapunov dimension (Kaplan-Yorke dimension), Multistability, and Hybrid
projective synchronization (HPS). Various dynamic behavior are observed such as hyperchaotic, chaotic, chaotic 2-tours,
and periodic behaviors. The paper provides proof of the main results through theoretical analysis and numerical simulations
conducted in MATLAB V2021.
