Figure 11 shows a frequency response plot (Bode plot) of a PV disturbance for the temperature loop, TIC-301, used in the example for a self-regulating, second-order process response. The aggressive ...

Even before loop tuning starts, the design may have created a slow-to-respond control loop with built-in lag. For example, a temperature sensor positioned a long distance from a heater can slow ...

Both of our open-loop control system examples above could easily be converted to closed-loop systems. A more advanced light switch might take input from a photo cell, ...

Both of our open-loop control system examples above could easily be converted to closed-loop systems. ... The “tighter” the tuning of the loop, the more prone it is to start oscillating ...

In a nonlinear world, the challenge of advanced loop tuning is to keep continuous and batch processes, as well as discrete operations, functioning cleanly and productively without unplanned downtime.

Technavio’s new market research report on the global PID loop tuning software market provides an analysis of the most important trends and drivers.
