Robust stability analysis of predictive PID controller or first-order system
一阶系统预测PID控制器鲁棒稳定性分析

The paper proposed input and output robust stability analysis of predictive PID control based on DCS(distributed control systems),aimed at first-order plus dead-time model,by using Kharitonov theorem and edge theorem.It gave the largest process parameters ranges when the system's parameters were 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.
