Abstract: We studied a sample of pulsing variable stars of $\delta$ Scuti type. Atmospheric parameters of the stars AO CVn, KW Aur and CP Boo were defined and specified based on high-precision spectroscopic data. The chemical composition of these stars relative to solar abundances was determined by differential analysis.

Keywords: $\delta$ Sct stars, chemical composition, atmospheric parameters.
