原料预热温度的模糊PID-神经元控制

针对具有不确定性、大纯滞后的催化裂化反应再生装置原料预热温度控制,提出了一种模糊PID-神经元控制方法.从介绍催化裂化反应再生装置原料预热被控对象的建模、神经元非模型控制和公式化的模糊控制方法人手,建立了模糊PID-神经元控制系统,设计了模糊神经元混合控制器,并使用神经元来在线调整模糊PID控制器的模糊规则.仿真实验结果表明所提出的模糊PID-神经元控制方法具有强鲁棒性,能有效控制具有大纯滞后和不确定性的对象.

Fuzzy-PID-neuron control for feed preheating plant

The fuzzy-PID-neuron control method is proposed for the FCCU Reactor-Regnnerator Feed Preheating plant.The model of the FCCU Reactor-Regenerator Feed Preheating plant is described.After discussing the neuron model-free control method and a formu- lation fuzzy control system,the fuzzy rules of the fuzzy-PID controller is tuned on-line by the neuron.Considering the plant with big un- certainties and grave delay time,the fuzzy-PID-neuron control system is set up and the model-free controller is designed.The simula- tion tests of the FCCU Reactor-Regenerator Feed Preheating plant are made under the conditions when the plant characteristics change a lot.The results demonstrate that the proposed controller has strong robustness and adaptability and is effective in controlling the plant with grave delay time and uncertainties.
