| 摘 要： | 针对生产过程中存在的滞后性、时变性、不确定性和变工况等特点,建立基于不同工作点的局部模型,将基于隶属度函数和基于加权和形式的思想相结合,对传统内模控制进行改进,提出了一种基于隶属函数的多模型内模控制方法。通过对某火电厂的过热汽温控制系统的仿真表明,多模型内模控制与单内模控制和常规PID控制相比较,在稳定性、鲁棒性和响应速度等方面,均具有明显的优越性和较好的控制品质。

| Abstract: | Considering the characteristics of time delay,time variables,uncertainties and variable operation condition in process control system,the partial models are built based on the different operating points,integrating fuzzy membership function with weighted sums to improve the traditional internal model control(IMC).The multiple model internal model control(MM-IMC)based on fuzzy membership function is also presented.The simulation example,the superheated steam temperature control system of power plant,shows th... |
