Embodiment Construction
[0030] A control method for a catalytic cracking unit of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Such as figure 1 Shown, a kind of control method of catalytic cracking unit, comprises steps:
[0032] S1. Determine the controlled variable in the catalytic cracking unit, the controlled variable is the temperature of the cyclone separator and the coke content of the regenerator;
[0033] S2. Based on the parameterized mathematical model of the catalytic cracking unit, obtain the optimal setting value corresponding to the temperature of the cyclone separator and the coke content of the regenerator;
[0034] S3. Obtain the data set of input variables and output variables, establish a prediction model for the coke content of the regenerator, and perform online prediction of the coke content of the regenerator;
[0035] S4. Using the feedback controller to perform online closed-loop con...
