Embodiment 1
[0030] Embodiment one: see figure 2 , the batch production process product quality control method based on two-layer hybrid intelligent optimization is characterized in that a two-layer intelligent hybrid optimization algorithm is used in the optimization control of the batch production process. This algorithm combines the advantages of PSO algorithm and SQP algorithm, It has the characteristics of high speed and high precision in solving complex problems. The specific operation steps are as follows:
[0031] (1) Data acquisition: collect the on-site operation data of batch production equipment in industrial production, summarize the operation experience of comprehensive historical data analysis, and determine the input variables and target variables of the soft sensor model;
[0032] (2) Data processing: Perform data preprocessing on the actual industrial device operation data collected in step (1), remove some data points under abnormal working conditions, and construct a s...
Embodiment 2
[0046] This embodiment is basically the same as Embodiment 1, and it can be said to be an example in Embodiment 1. In this embodiment, the optimal control of the batch processing unit includes determining the optimal operation trajectory and implementing the tracking of the optimal operation trajectory. Here, the optimal The operation trajectory refers to the change curve of the control variables that are easy to measure during the production process, such as temperature, flow rate, volume, etc., during the entire production process. This patent mainly focuses on the operation variable of temperature, and the following will use the temperature track as the product quality control operation track.
[0047] (1) Data acquisition: collect the operation data in the batch production process through the data acquisition device: reaction temperature and product end-point quality. Data were processed using screening, normalization, and outlier methods as follows:
[0048] Screening: e...
