【Abstract】 In this note, we apply the observer to the identification of the unknown parameters of the Lorenz chaotic systems. The simulations show that when the unknown parameters are constant or slow time\|varying, the method we present is also successful. Next, we synthesize the identification and the control problem. An improved method for controling Lorenz chaos has been presented. Simulation has shown the effectiveness of the results.更多还原
