Method and apparatus for adjusting parameter of process controller

摘要

The present invention relates to a method and an apparatus for adjusting parameters of a process controller and includes a filter F and a feature quantity calculating unit C, a tuning parameter calculating unit T, a controller gain extracting unit C, a signal analyzing unit S ) And a graphic monitor (M), and the input signal and the output signal of the plant are applied to the tuner to determine the current state, and the PI gain value of the PI controller is obtained and monitored to monitor the state of the process control system signal You can see how the current control system has changed and how much it has changed compared to the past, and you can see if Alma's control has improved when changing the gain. In addition, in synchronizing industrial controllers, existing skilled workers can quickly synchronize with time and effort through trial and error methods, thereby improving productivity.
