Abstract

A tracking simulator models an industrial process simultaneously and in parallel with the industrial process. The simulator receives control inputs provided by an automation system to control the industrial process. Based on these inputs, the simulator with its process model(s) provides simulated process outputs. In order to avoid divergence of the simulation models from the real process, the tracking simulator receives process measurements from the real process and is able to correct, i.e. update, its models based on these real process measurements and the simulator outputs. One or more of the updated or adjusting parameters for the simulation models are generated by PI or PID controller. Additionally, some of the updated parameters can be generated by an NM or SE method. The PI or PID controller can be an automatic controller tuning tool of the automation system. Additionally, some of the updated parameters can be generated by NM.
