Embodiment Construction
[0069] The present invention obtains a controller of dissolved oxygen DO concentration in the sewage treatment process based on self-organized radial basis SORBF neural network; the controller analyzes the sewage treatment process by constructing a SORBF neural network model, changes the structure of the neural network in real time, and utilizes The method of model prediction controls the aeration amount in the sewage treatment process, so as to achieve the purpose of controlling the DO concentration;
[0070] The experimental data comes from the daily water quality analysis report of a sewage treatment plant; after the experimental samples are preprocessed, 400 sets of data are left, and all 400 sets of data samples are divided into two parts: 240 sets of data are used as training samples, and the remaining 160 sets of data as a test sample;
[0071] The present invention adopts following technical scheme and implementation steps:
[0072] 1. the design of the dissolved oxyg...
