.Modelica.Clocked.RealSignals.Sampler.SuperSampleInterpolated

Information

This block super-samples the clocked Real input signal u and provides it linearly interpolated between the u-values as clocked output signal y.

To be more precise: The clock of y is factor-times faster than the clock of u. At every tick of the clock of y, the value of y is set to the value of the linearly interpolated value between the last available values of u. The first activation of the clock of y coincides with the first activation of the clock of u. By default, the super-sampling factor is inferred, that is, it must be defined somewhere else. If parameter inferFactor = false, then the super-sampling factor is defined by Integer parameter factor.

For control applications, this block is better suited as block SuperSample since it does not induce "vibrations".

Example

The following example samples a sine signal with a periodic clock of 20 ms period, and then super-samples the resulting clocked signal with a factor of 3 and interpolates the result linearly:

	model	simulation result

As can be seen, block superSampleIpo introduces 3 additional clock ticks for the output y and determines the values at these clock ticks, so that the last two available values of the input u are linearly interpolated. The super-sampling factor = 3 is displayed in the icon of the superSampleIpo block. Note the up-arrow in the icon of the SuperSampleInterpolation block indicates that the clock of superSampleIpo.y is faster as the clock of superSampleIpo.u.
