The Lorenz system is chaos when parameters vary in certain scope. In order to control chaotic Lorenz system, a new controller is proposed based on tridiagonal matrix stability theory. The proposed controller is simple and easy to be implemented. Simulation results show the effectiveness of the controller.


Key words: control chaos, Lorenz system, tridiagonal matrix stability theory.
