时变大时滞系统的一种智能控制策略

An Intelligent Control Stratagem for Time-varying Large Delay System

针对具有复杂非线性特征的时变大时滞系统,本文提出了一种新的智能控制策略。该方法利用遗传算法来辨识系统的时变时滞,用改进的自适应向量遗忘因子法来辨识系统的时变参数,然后利用Smith预估器对系统进行预估补偿控制,取得了良好的控制效果。

An intelligent control stratagem is proposed for time-vary large delay system that have complex nonlinear characteristic. In this method, GA is used to identify the time-varying delay, and improved adaptive vector forgetting factor is used to identify other time-varying parameters of system, then Smith predictor is applied to compensate delay. The simulation results indicate the effectiveness of this method.
