Multivariable (MIMO) processes call for a controller that models the process as a whole, not a collection of unrelated loops.

Our patented algorithms derive the system model and controller from real-time process data, automatically.

Modeling is automatic

  • No "expert" needed
  • Controller generation is fast and easy
  • Your process describes itself!

Flexible and adaptable

  • Easily adapted for different control objectives
  • Works on square and non-square systems
  • Heterogenous or homogenous process variables

Easy to configure and use

  • Fine-tune speed and damping, directly
  • Simple process variable configuration from graphical user interface


We're experts in every aspect of model based control. From design through deployment, nTrolus can partner with you to put your processes under optimal control.
