Simple step-by-step tuning procedure

Tuning is made easy: just click on the orange button (like the Start button in the picture), and you end up with optimally tuned PID loops. The PID Tuner guides you through a step-by-step procedure, but in each step you can make any adjustments you like. After all, you are in charge.

Connect to any control hardware and simulation software

The PID Tuner communicates with 'others' via OPC. Therefore, connect to any controller hardware, such as :
  • Siemens PLCs
  • Allen Bradley PLCs
  • Arduino

In addition, connect to any simulation software, such as:
  • Matlab
  • Simulink
  • gProms
  • Aspen Technology

Tune multiple PID loops that interact

The PID Tuner can tune mutiple PID loops that interact with each other. It does so by minimising a mathematical cost function, subject to the model that you created previously, with step tests.

Improve your PID loops with add-ons

The PID Tuner can tune add-ons to the PID controller like feedforward and decoupler as shown in the figure (FF = Feedforward, DEC = Decoupler, DV = Distrubance Variable, MV2 is the manipulated variable of another PID). These rascalls are simple to program, but can be hard to tune. With the PID Tuner, tuning them is easy, and moreover, you can evaluate their effectiveness in advance, before you program them.

Minimize risks

PID tuning in a production envrionment can be risky. Why? Firstly, because PID controllers usually perform best when they are tuned 'tightly' (close to their stability limit); mistakes may lead to production losses. Secondly, in order to tune PID controllers efficiently, you need to perform tests during (normal) production. The PID Tuner helps to reduce risks, both during the tests, and tuning. In the screenshot you can see that we set PVmax (maximum on the controlled Process Variable) to 12, and as a result, the step test was stopped as soon as the PV exceeded 12. After that, control switched back to PID control, with the old settings.

Monitor the loops on-line

Monitor in real-time how the PID controller(s) behave(s), i.e. watch the controlled variable(s), the manipulated variable(s), and any other tags you want to add.

Evaluate different control options off-line

Use the interactive off-line simulation environment to evaluate what-if scenarios: does it pay to use PID instead of PI control? Will Feedforward help? Compare performance between 'old' and 'new' settings, and check if it is worthwile to program add-ons like feedforward, or tune the PID more 'tightly'. Manually adjust settings, or use our tuning tools, and immidiately watch the simulated effect on your loop(s), process variables, and manipulated variables.

Automatic Report Generation

Once the PID loop(s) (and optional add-ons) have been tuned and tested in real-life, a report (Click here for an example) is generated that shows the performance with both the old and new settings. Use it for future reference,or to impress your boss.

Pay for results

We want to make sure that our software does what it should do: allow you and your colleagues to use our software as we intended and promised. Therefore, we just want to be paid to gaurantee this. Hence, we do not send you the software with instructions and wish you good luck, but, instead, we make sure it works for you.
