MFA Control Toolset for
NI LabVIEW™ - Professional Edition
The MFA Control Toolset for LabVIEW Pro Edition software includes embedded Model-Free Adaptive (MFA) controllers for the LabVIEW environment. NI platforms include PC, PXI, FieldPoint, Compact FieldPoint and CompactRIO. In LabVIEW Real-time, MFA can run faster than one millisecond providing powerful high-speed adaptive control capability for equipment control. The included standard MFA controller VIs (Virtual Instruments) and special MFA controller VIs are listed in the following tables.
MIMO MFA controllers are only available in the Professional Edition. Each MIMO will consume a corresponding number of SISO MFA controllers. For example, if the user has a CLP-04D package, he/she can run the following number of controllers at the same time: 4 SISO MFAs, or 2 SISO MFA and 1 2x2 MFA, or 2 2x2 MFAs, or 1 SISO and 1 3x3 MFA, or 4x4 MFA, and so on. This makes the product very flexible for lab or prototyping use.
Standard MFA Controller VIs |
Capability and Usage |
SISO MFA |
Replaces PID to eliminate manual tuning. |
Nonlinear MFA |
Controls extremely nonlinear processes. |
MFA pH |
Controls pH processes. |
SISO + Feedforward MFA |
Compensates for measurable disturbances. |
Anti-delay + Feedforward MFA |
Controls processes with large time delays or large Tau/T Ratio. |
Robust MFA |
Protects the process variable from running outside defined boundaries. |
Special MFA Controller VIs |
Capability and Usage |
Flex-phase MFA |
Controls open-loop oscillating processes. |
Anti-inverse MFA |
Controls processes that change signs. (This is also called MFA Optimizer) |
Time-varying MFA |
Controls processes with varying time constants and varying time delays. |
Anti-delay MFA pH |
Controls pH processes with large and varying time delays. |
2x2 MFA |
Controls 2x2 multivariable processes. Need CLP-02-Pro or larger. |
3x3 MFA |
Controls 3x3 multivariable processes. Need CLP-03-Pro or larger. |
4x4 MFA |
Controls 4x4 multivariable processes. Need CLP-04-Pro or larger. |
5x5 MFA |
Controls 5x5 multivariable processes. Need CLP-05-Pro or larger. |
VIs with Auto-Calibration Features |
Capability and Usage |
| SISO MFA 2 |
Replaces PID to eliminate manual tuning. |
| Nonlinear MFA 2 |
Controls extremely nonlinear processes. |
| MFA pH 2 |
Controls pH processes. |
| SISO + Feedforward MFA 2 |
Compensates for measurable disturbances. |
| Anti-delay + Feedforward MFA 2 |
Controls processes with large time delays or large Tau/T Ratio. |
| Robust MFA 2 |
Protects the process variable from running outside defined boundaries. |
| Nonlinear + FF MFA 2 |
Controls nonlinear processes with disturbances. |
Note for Auto-calibration: You can save the adaptive factor and re-load it when the equipment changes or restarts.
