Abstract

This paper shows the development of a control strategy for a digitally controlled Michelson Interferometer inside of a MIDAC Fourier Transform Infrared (FTIR) spectrometer. Initial investigation has shown undesirable response characteristic, primarily due to locations of the zeros of the system. The effect of the zeros on a general second order case will be studied and the definitions of the poles and zeros for the multivariable system are summarized. Techniques to compensate for the undesired location of zeros are derived and applied to the control of the interferometer under investigation.
