| 摘 要： | 根据火电厂过热汽温的动态特性，将先进的预测控制算法和PID控制算法相结合，构成DMC-PID串级控制系统。利用DMC预测控制算法的鲁棒性强及PID控制算法抗干扰性能好的优点，在Matlab平台上进行了仿真，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. |
