Calibration Curves: Linear Least Squares

1.2K
A calibration curve is a plot of the instrument's response against a series of known concentrations of a substance. This curve is used to set the instrument response levels, using the substance and its concentrations as standards. Alternatively, or additionally, an equation is fitted to the calibration curve plot and subsequently used to calculate the unknown concentrations of other samples reliably.
For data that follow a straight line, the standard method for fitting is the linear...

Plotting and Calibrating the Root Locus

91
Root loci often diverge as system poles shift from the real axis to the complex plane. Key points in this transition are the breakaway and break-in points, indicating where the root locus leaves and reenters the real axis. The branches of the root locus form an angle of 180/n degrees with the real axis, where n is the number of branches at a breakaway or break-in point.
The maximum gain occurs at the breakaway points between open-loop poles on the real axis, while the minimum gain is...

Main Methods:

  • Utilized augmented reality markers for initial pose estimation of AUPA units.
  • Employed thermal imaging to map pressure distribution based on estimated poses.
  • Applied Bayesian optimization to refine pose parameters and minimize focal point error.

Main Results:

  • Successfully demonstrated an image-processing-based calibration technique for AUPAs.
  • Achieved efficient and accurate calibration of relative AUPA unit poses.
  • The method is effective even for AUPA units in challenging-to-measure locations.

Conclusions:

  • The developed method offers a significant improvement over manual calibration for AUPA systems.
  • This advancement facilitates more complex and dynamic configurations of AUPA units.
  • Enhanced calibration accuracy supports improved performance in tactile feedback and acoustic levitation.
