[0044] Penicillin (penicillin) Penicillin (penicillin) is a very broad clinical value of antibiotics. This paper uses the international platform Pensim2.0 simulation platform to conduct fault monitoring research on the penicillin fermentation process.
[0045] In this platform, for the convenience of the experiment, the working conditions were set as 400 hours for each batch of continuous fermentation, and the sampling interval was 1 hour. The initial conditions of each batch were slightly changed within the allowable range. 40 batches of normal data are used for simulation, and 10 process variables are selected to obtain 40×400×10 data for offline modeling. The process variables are shown in Table 1. In order to better simulate the actual production situation, a certain amount of Gaussian noise interference is added to the training samples. In order to verify the performance of the proposed method in fault monitoring, this paper selects three groups of fault batch samples ...
