Optimally tune your PID controller during production without risks

8.7/10 (31 Ratings)

Using the PID Tuner, you can tune the PID optimally in both open and closed-loop (while it runs), without any risk, i.e. production quality is not affected.

The PID Tuner tunes a PID controller based on a model of the system or process it needs to control. This model is obtained from actual data of your machine/system. The procedure to obtain such a model is referred to as identification.

Supports both on-line and off-line mode.

In on-line mode, the data is obtained in real-time through OPC DA communication. These data are automatically stored within the project file.
In off-line mode, you can import data from files (csv format).

Extensive Model Identification Options

The PID tuning requires a System Model, and this model is usually obtained from data (model identification). The PID Tuner does not only support identification of the First Order Time Delay (FOTD) models, but also (Second Order Time Delay) SOTD models.

Supports tuning of all PID types

Supports all PID types, among which DeltaV, Siemens, Omron, Rockwell , Yokogawa. Different vendors use different PID types. Therefore, we included all options: the parallel form, direct form, proportional band format and setpoint weight parameters. Scaling parameters, often not published, are found by automatic fitting.
The PID Tuner supports tuning not only the P, I and D constants but also setpoint weighting,
