摘　　要：针对火电厂主蒸汽温度的时变性特征,设计了基于多模型的串级PID控制系统,并以某电厂锅炉5个局部工作点的主蒸汽温度为对象进行了仿真。仿真结果表明,基于多模型的串级PID控制策略能够较好的解决主蒸汽温度的时变性问题,其控制效果也相对较好。Considering thermal power plant＇s time-varying characteristics of steam temperature system, the paper relates the design of multi-model based PID cascade control system. ,and for the main steam temperature a power plant＇s boiler＇s five local operating point has been simulated. The simulation results show that the model based on multi-PID cascade control strategy resolves the main steam temperature of time-varying problem better ,and the effect of the control is relatively good.
