摘要: 定量分析了单输入单输出(SISO)动态矩阵控制系统的鲁棒稳定条件,采用脉冲响 应模型簇来描述被控过程的不确定性,并讨论了基于脉冲响应模型(FIR)的动态矩阵控制 (DMC)算法;在此基础上,推导了DMC闭环系统的鲁棒稳定条件.Abstract: This paper presents the robust stability conditions for single-input/single-output (SISO)dynamic matrix control (DMC) algorithm. Model uncertainty is described by using a range of possible plant impulse responses, and a new form of DMC algorithm based on a finite impulse response (FIR)model is discussed. Then the robust stability condition for the new DMC algorithm is derived based on Jury's dominant coefficient lemma. These results provide theoretical foundations for analyzing and designing predictive control systems.
