Embodiment Construction
[0062] The following is a specific description of the penicillin fermentation process failure detection method of the present invention through exemplary implementations.
[0063] The invention provides a method for fault detection in a penicillin fermentation process, the specific steps are as follows:
[0064] Step 1: Collect multiple batches of normal production process data. The complete data set X(I×J×K) of I batch of normal production is a three-dimensional data structure, where I represents the number of batches, J represents the number of process variables, and K Represents the number of samples. Such as figure 2 As shown, the three-dimensional data set is expanded to the right along the time axis to form a series of two-dimensional data sets (I×JK), and K time slices are obtained, that is, K two-dimensional data subspace models Xi (i=1,2 , L, K). In the two-dimensional data subspace model, each row element contains the process data of all process variables of a ba...
