Nonlinear Systems VIs (FPGA Module)
Owning Palette: Control VIs
Use the Nonlinear Systems VIs to model nonlinear systems on FPGA targets.
 | Note This palette is specific to FPGA targets. |
| Palette Object | Description |
|---|---|
| Backlash | Implements a backlash or deadband function. output does not change until input differs from the previous output by at least half of deadband. The largest data type you wire to any input determines the polymorphic instance LabVIEW uses. |
| Boolean Crossing | Detects state changes of Boolean input points. You can choose from three detectors: either, false-true, or true-false. |
| Dead Zone | Provides a region of zero output, or a dead zone. output is zero if start of dead zone <= input <= end of dead zone. The largest data type you wire to any input determines the polymorphic instance LabVIEW uses. |
| Friction | Implements a discontinuity at zero with linear behavior elsewhere. The larger data type you wire to input or offset determines the polymorphic instance LabVIEW uses. |
| Memory Element | Stores the input value and returns it on the next call. |
| Quantizer | Quantizes an integer input signal using fixed-point rounding. |
| Rate Limiter | Specifies a maximum rate of change of a signal. The largest data type you wire to any input determines the polymorphic instance LabVIEW uses. |
| Relay | Switches between the output when on and output when off inputs. When the relay is on, it remains on until input is less than switch off point. When the relay is off, it remains off until input is greater than switch on point. The relay is off by default. The largest data type you wire to any input determines the polymorphic instance LabVIEW uses. |
| Saturation | Limits the valid range of a signal to that specified by Upper limit and Lower limit. You can configure the VI to specify the integer or bit limits and signed or unsigned inputs. |
| Switch | Switches between two input values based on the value of control input. The largest data type you wire to any input determines the polymorphic instance LabVIEW uses. |
| Trigger | Detects changes of the input signal during a control or simulation process. |
| Zero Crossing | Detects zero crossings of an integer input signal. |
