MFA Control Toolset for NI LabVIEW – 专业版

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 2×2 MFA, or 2 2×2 MFAs, or 1 SISO and 1 3×3 MFA, or 4×4 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.
2×2 MFA
Controls 2×2 multivariable processes. Need CCLP-02 or larger.
3×3 MFA
Controls 3×3 multivariable processes. Need CCLP-03 or larger.
4×4 MFA
Controls 4×4 multivariable processes. Need CCLP-04 or larger.
5×5 MFA
Controls 5×5 multivariable processes. Need CCLP-05 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.
