Abstract The chaos control of parameter –dependent chaotic systems is an important step in many applications. The goal of the control is to stabilize the parameter –dependent chaotic systems . The control parameter is determined through a sensitivity study to obtein the most sensitive parameter that affects the system behavior. The overall system dynamics is governed by the control parameters. The L2 norm is a simple method that determines the most efficient parameter among system parameters. It avoids the disadvantages of the method of sensitivity function approach, such as numerical stability and solving large dimensional system. The results of the study on Chua system show the robustness of the proposed algorithms.
