摘要： 设计了具有扇区非线性和死区的多输入不确定Lorenz系统的滑模变结构控制器,从理论上证明了该控制器的有效性.在该控制器作用下,受控Lorenz系统可以迅速到达任意目标轨道,且不受输入的扇区非线性和死区、参数的不确定性及外部噪声的影响,具有很强的鲁棒性.最后通过对受控Lorenz系统的仿真研究,验证了该控制器的有效性.

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
