一种基于模型参考自适应内模原理的主汽压力控制

Main Steam Pressure Control System Based on Model Reference Adaptive with Internal Model Theory

基于常规模型参考自适应控制原理,用模糊逻辑作为自适应机构,内模控制器作为调节器,综合了模糊控制、内模控制和自适应控制的优点,将该方法应用于电厂主汽压力控制。仿真研究表明,与其它方法相比,其控制效果最佳,并能适应对象参数特性的大范围变化。

A control scheme is presented based on the general model reference adaptive control theory,using fuzzy logic as adaptive unit and internal model controller as adjustor. The scheme integrates all the advantages of internal control, fuzzy control and adaptive control. It is applied to the main steam pressure system in power plants. The simulation results show that its performance is improved compared with other schemes.
