Certain processes require a single PID controller to drive two different final control elements (FCEs). The most common method is split-range control. This strategy essentially breaks the controller output into ranges in which a portion of the output drives one FCE while another portion moves an alternate FCE. The most common application is temperature controller where the PID is programmed to drive both cooling and heating elements. In order to handle a process’ behavior effectively, applications like temperature control require special attention to both controller programming and PID tuning.
During this webinar, Dr. Bob Rice will review how to properly design and tune a PID controller for use in split-range. Dale Reed will then review how to apply the Control Strategy Templates and use Studio5000 to implement this control strategy within PlantPAx.
