• XMC® is an innovative patented model-less multivariable constraint control and optimization technology. It is industry's only model-less multivariable control method.

  • By eliminating dependence on detailed models, XMC® is less expensive, less complex, more agile, and more user-friendly, at every life-cycle stage. Many life-cycle stages, such as modeling and model maintenance, are eliminated completely!

  • XMC® is ideal for applications that have fallen into the APC application gap, or as an alternative to many high-maintenance legacy model-based applications.

  • XMC® is innovative. It utilizes a patented model-less multivariable control method and embeds patented Rate-Predictive Control (RPC®), industry's only inherently adaptive control method, as its internal control method.

Find out more about RPC® and XMC® by contacting APC Performance, LLC, or Lin & Associates, Inc. regarding an evaluation licsense for RPC® or XMC®

Take one of the following steps to explore what XMC® or RPC® can bring to your process automation program:

  • Install a crude oil atmospheric tower simulation and XMC® controller on your DCS platform and take XMC® for a "test drive".
  • Request a trial XMC® license for any application and APC Performance will work with you to assure a successful application.
  • Request a trial RPC® license, which can be deployoed in less than 1 hour, to solve any problematic loop performance that will benefit from RPC's adaptive capabilities, operational performance, or dead-time control capabilities.
  • There is no cost for trial/evaluation licenses.
  • Inquiries may be directed to either APC Performance or Lin & Associates.
