APC-Sensor intelligent soft sensor and flowsheet calculation software uses the technology of neural networks and first principle modeling as its core, integrated the function of data pre-processing, secondary variable selection, off-line modeling & simulation , and on-line prediction . It is an important assistant software in process operation and advanced process control. It has the following function:
¡ô Provide fast, reliable and accurate values of the key process variables in the process units
¡ô Provide first principle models for specific process units in hydrocarbon process industries (HPI) and chemical process industries (CPI)
¡ô Use special two-fold technology of model prediction update , including predictive model receding update and laboratory data error update , to improve the precision of online prediction.
