Research And Application Of Advanced Process Control Technique On Continuous Catalytic Reforming Process

4. For the problem that the model errors of soft sensor would greatly affect the accuracy of the soft sensor, a triple soft sensor error correction method which contained error correction, model parameters correction and model structure correction was presented. The method is directly data-driven, easy to achieve, and used to CCR aromatics yield soft measurement achieved good results.5. The last part of the thesis is summary and perspective.
