Abstract :
In this paper, eight groups of chaotic attractors including hyperchaotic attractor of a four-order Chua´s circuit with a piecewise-linear nonlinearity are presented and a simple method to control chaos oscillation for this circuit is proposed by exploiting absolute stability theory in nonlinear systems. A linear feedback controller is derived based on linear matrix inequality (LMI). Numerical simulations are presented to illustrate the efficiency of the proposed method.
