What is Intelligent Autotune?


Wavelength’s proprietary IntelliTune® algorithm characterizes the TE / Sensor system’s response to the TC LAB temperature controller and then automatically adjusts the PID control values as setpoint, tuning mode, or bias current are changed.

  1. Run IntelliTune with the setpoint at least 5°C off ambient and watch the TC LAB instrument adapt the PID settings to a much higher or lower setpoint.
  2. After a single characterization scan, explore either optimized Setpoint Response or Disturbance Rejection performance to see what tuning mode works best with your load.
  3. Try the system with or without the D term to see if noise reduces stability around the setpoint.

With IntelliTune’s ability to recalculate control values, the temperature controller becomes a tool for speeding up experimental studies. Questions like “What are the best PID control coefficients to use?” can now become “Which mode achieves best stability fastest?” or “Should I use the D term or leave it out?”. These are quickly and easily answered.

We ran a series of tests that highlighted the differences between the TC10 LAB instrument with IntelliTune and three competing instruments that use various conventional autotune algorithms. With a single scan, IntelliTune was able to characterize a load and automatically adjust the PID coefficients for changes in mode, setpoint, or control parameters (such as turning the D term OFF). The instruments using the traditional autotune algorithm required recalibration for each scenario to achieve optimum performance.
