摘　　要：基于CGT(Command Generator Tracker)理论的模型输出跟踪控制可实现对低阶理想参考模型的性能跟踪。然而,当被控对象会随环境变化而改变时,控制系统的跟踪性能会有所下降。为了进一步提高控制系统的适应性,提出了一种基于CGT的自适应模型输出跟踪控制方法。该方法通过在线辨识系统参数,自动调整前馈输入,从而提高控制系统的跟踪性能。随后,针对网络化铝板温度系统应用了提出的基于CGT的自适应模型输出跟随控制器。实验验证了控制方法的有效性,实现了对铝板温度的网络化跟踪控制。Model output following control based on CGT （Command Generator Tracker） theory can be used to track the output of the low order reference model with constant parameters. However, when the controlled object is changed with the environment, the tracking performance will decline. In this paper, an adaptive model output following control method based on CGT is proposed to improve the adaptation of the control system, where the feedforward controller is adjusted adaptively according to the online identified model. That is, the adaptive feedforward input related to the parameters of the model can improve the tracking performance of the system. Then, its application is discussed for a networked control of aluminum temperature process. Experimental results show that the networked tracking control of the aluminum temperature is realized, which demonstrates the effectiveness of the proposed method.
