结果表明该控制策略具有明显优于常规PID串级控制的性能。

Abstract

Based on dynamic characteristics of superheated steam temperature in thermal power plants

a DMC-PID cascade control system has been constructed by combination of advanced predictive control algorithm with propertional-integral-derivative(PID)control algorithm.Taking advantage of strong robustness of DMC predictive control algorithm and good counter-interfeerence capability of PID control algorith

a simulation has been carried out on the Matlab platform.results show the above-mentioned control strategy has obviously better perormance than conventional PID cascade control.
