Design Level of Operation for the Jacketed Stirred Reactor Process
ABSTRACT: Like the heat exchanger and gravity drained tanks case studies, the jacketed stirred reactor is a self regulating processes. That is, the measured process variable (PV) naturally seeks a steady operating level if the controller output (CO) and major disturbance (D) are held constant for a sufficient length of time.
Modeling the Dynamics of the Jacketed Stirred Reactor with Software
ABSTRACT: The control objective of the jacketed reactor case study, shown below and discussed in detailed in this article, is disturbance rejection. More specifically, we seek a controller design that will minimize the impact on reactor operation when the temperature of the liquid entering the cooling jacket changes.
Exploring the FOPDT Model With a Parameter Sensitivity Study
ABSTRACT: Step 3 of the PID controller design and tuning recipe is to approximate process bump test data by fitting it with a first order plus dead time (FOPDT) dynamic model. Data from a proper bump test is rich in dynamic information that is characteristic of our controller output (CO) to measured process variable (PV) relationship. A FOPDT model is a convenient way to quantify (assign numerical values to) key aspects of this CO to PV relationship for use in controller design and tuning.
