Interactive Tool about control signal saturation (windup) with PID control

The purpose of this module is to give a familiarity with the phenomenon of integral windup and a method for avoiding it. The module shows process outputs and control signals for unlimited...

Nonlinear Control Output Signal Characterization

If the process gain makes large changes over the operating range, then tuning PID (or other linear) controllers is difficult.  If tuned for one region, the controller is undesirably sluggish...

Bumpless Transfer and Tuning

Switching from MAN to AUTO mode or LOCAL to CASCADE or changing the controller integral time should not cause a change in the controller output, a bump.  But a primitive coding of the PID...

Interactive Tool for Loop Shaping understanding based on PID control

Loop shaping is a design method where it is attempted to choose a controller such that the loop transfer function obtains the desired shape. In this module the loop transfer function is...

Orifice Calibration

The ISO method for orifice design and calibration is grounded in the ideal square-root relation between pressure drop and flow rate, specifies the in-pipe structure for an orifice, and...

Scaled Transmission Signals, Engineering Units, and Conversions

Information is transmitted in scaled signals (4-20 mA, 3-15 psig, 0-100%, digital counts), which are also deviations from some reference vales (such as psi gage is to psia).  But process...

Ratio Control and Scaled Signal Calculations

When and how to use Ratio Control and use Scaled Signals

Interpreting Lines on PFDs and P&IDs

Lines on a process flow diagram (PFD) indicate material flow.  In contrast, on a piping and instrument diagram (P&ID), the control overlay for the PFD, the lines represent information flow. ...
