Model-Free Adaptive Control
MFA Controllers at a Glance
Features and Specifications
MFA controls the processes that are too difficult for PID controllers to handle. MFA is the only "No Model" advanced controller on the market that can control complex systems without the use of first-principle mathematical models or dynamic modeling based models. Once installed, no controller parameter tuning is required.

Better control means improved process stability, higher production efficiency and yield, consistent product quality, and reduced material and energy waste.

Includes 6 standard MFA controllers:

  • SISO MFA to replace PID to eliminate manual tuning,
  • Nonlinear MFA to control extremely nonlinear processes,
  • Anti-delay MFA to control processes with large time delays,
  • MFA pH to control pH processes,
  • Robust MFA to force PV to stay within defined bounds, and
  • Feedforward MFA to compensate for measurable disturbances
  • Configurable MFA and PID control.
  • Dynamic, logic, calculation blocks.
  • Trends, faceplates, historical data.
  • Optional HMI software.
  • Size: 222×160×47mm, WT: 1.42Kg.
  • Cutout dimension: 208x150mm.
  • Working Temp: 0 to 50 deg C.
  • Storage Temp: -20 to 70 deg C.

    Suitable Control Applications:
  • Water pH, ORP, and Turbidity,
  • Combustion and temp of small boilers, ovens, furnaces, and HE,
  • Density, temp, moisture and level of food processing equipment, etc.
