Abstract

Abstract: The input and output robust stability analysis of predictive PID control based on DCS（Distributed Control Systems）is proposed,aimed at non-minimum phase model by using Kharitonov theorem and Edge theorem.The largest process parameters ranges are given when the system’s parameters are uncertainty.The theoretic analysis and simulation results demonstrate that this control algorithm has better robustness than PID control algorithm when the process parameters are far away from the nominal value.

Key words: Distributed Control System（DCS）, PID control, predictive control, robust stability, characteristic polynomial, non-minimum phase model

摘要： 针对基于DCS的预测PID的控制系统,利用Kharitonov定理和边缘理论分析其在参数不确定情况下输入输出鲁棒稳定性。具体对NMPS（非最小相位系统）给出了系统保持稳定的最大过程参数区间。理论和分析仿真结果表明,当过程参数偏离标称值时,该算法能使系统保持很好的鲁棒稳定性。
