Video: Integral Tracking for the Hot Air Dampers
2015-09-21 22:09:00| Chemical Processing
Should a hot air damper be driven either fully open or fully closed, integral tracking must be activated in either the hot air pressure controller or the bag house inlet temperature controller. The issues are similar to those for output tracking presented in a previous video. To access the entire video series from Cecil Smith, visit our video page. Cecil Smith is president of Cecil L.

Video: Integral Tracking for the Hot Air Temperature Controller
2015-09-21 22:05:00| Chemical Processing
For a PID controller to perform as expected, changes in the controller output must lead to changes in the opening of one or more final control elements, which must affect the measured variable for the PID controller. Driving a final control element to either limit disrupts this sequence. This requires integral tracking, not output tracking. If the final control element has been driven fully open, control actions to increase the opening cannot be implemented, but control actions to decrease the opening can be. The opposite is true if the final control element is driven fully closed. To access the entire video series from Cecil Smith, visit our video page. Cecil Smith is president of Cecil L.
