Abstract

Abstract: We design a controller for uncertain Lorenz systemes with multiple inputs containing sector nonlinearity and deadzones,and demonstrate its effectiveness theoretically.With this controller the controlled Lorenz system drives system orbits asymptotically to arbitrarily objective trajectories evenif there exist uncertainties,deadzones and sector nonlinearities in the inputs.Finally,by emulation studies of controlled Lorenz systems,effectiveness of the controller is demonstrated.

Key words: chaos, sliding mode control, sector nonlinear, deadzone, multiple inputs, effectiveness
