Finding hidden attractors in improved memristor-based Chua´´s circuit

An improved memristive Chua´s circuit is proposed, from which some hidden attractors are found. This memristive circuit has three determined equilibrium points, including a zero saddle point and two non-zero saddle-foci. The two non-zero saddle-foci are stable for the specified circuit element parameters, leading to the generation of hidden attractors and coexisting hidden attractors. Additionally, the observed hidden attractors are not sensitive to the initial conditions, which can easily be captured in a physical circuit by adjusting the circuit element parameters to the desired values.
