Quantifying Dynamic Process Behavior 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 […]

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.
