Practical Process Control for Engineers and Technicians

Configure the five algorithms shown in Figure E.1, which include control and process simulation. The simulation consists of the tags SIM-FLOW, SIM1, SIM2 and SIM3. SIM-FLOW simulates the fuel flow of the feed heater and SIM1, SIM2 and SIM3 simulate the feed heater's outlet temperature. This simulation is very simplified, but it has stability problems as they would occur in reality. The control is cascade control and consists of the primary controller TC-03 (temperature control) and the secondary controller FC-04 (fuel feed control).
The following data assumes the use of a Honeywell basic controller. It should not be too difficult to implement the same configuration in any other controller.
