| 英文摘要 |
| The accurate control of oxygen content in flue gas is of great significance to the stable and efficient operation
of the municipal solid waste incineration plant. However, it is difficult to achieve effective control performance
of oxygen content in flue gas due to the inherent nonlinearity and uncertainty of the municipal solid waste incineration
process. Therefore, a data-driven predictive control scheme of oxygen content in flue gas is proposed for municipal solid
waste incineration process. Firstly, the prediction model based on the self-organizing long short-term memory (SOLSTM)
network is designed. The structure of the hidden layer is dynamically adjusted by integrating the activity and significance
of neurons, and then the prediction accuracy of oxygen content in flue gas is improved. Secondly, the gradient descent
method is utilized to obtain the control law, and the optimization efficiency is guaranteed. Thirdly, the stability of the proposed
control scheme is analyzed based on the Lyapunov theory. Finally, the effectiveness of the proposed control method
is verified based on the industrial data. Compared with other methods, the proposed method achieves stable and efficient
control performance for oxygen content in flue gas. |
