Advanced Process Control
Advanced Process Control

APC is a term that can include a range of advanced control methodologies. The common objective is to find a way to manage complex interactions within a process better than traditional regulatory control.

On the basis of conventional automatic control in process industry enterprises, Advanced Process Control adopts strategies such as multivariable predictive control, intelligent control, soft measurement and process calculation to realize energy saving and efficiency increase in production process, it also can improve the control quality of complex process, enhance the anti-interference ability and robustness of the system, and reduce manual labor intensity
