模糊自适应内模控制在超临界给水控制中的应用

Application of Fuzzy Adaptive Internal Model Control on Feed Water Control for Supercritical Unit

针对复杂多变、非线性、强耦合、大迟延的超临界机组给水控制系统,提出了一种基于内模的模糊自适应控制方案。通过仿真试验,可以得知模糊自适应内模控制算法可以显著提高给水系统的响应速度和稳定性,并且在抗干扰和模型自适应方面都优于常规PID控制和内模控制,具有较好的控制效果。

According to the complex, nonlinear, strong coupling and large delay supercritical unit feed water, the design method of control system fuzzy adaptive internal model is proposed. Through simulation experiment, it is known that this method of fuzzy adaptive internal model can significantly improve the response speed and the stability of the feed water system. In addition, this method is better than PID control and internal model control in anti-interference and model-adaptivity, and has a good control effect.
