A New Generation of Integrated Avionic Synthesizers

A phase-locked regulator system (PLRS) of separately exoited 1)C motors with e phase-frequency oomparator ia theoretically and experimentally atudied. For the phaao-frequency comparator a new non-linear but aimple model which explains the syatem behaviour very well is introduecd. System neyrnptotio stnbility is proved theoretically and stability eriterin era given. The effect of input ehangea on system performance is quanlitstively described. Finally it is ahown that thq thearctienl results are in very good agreement with measurements obtained from an actual system on the basis of whioh some practical design aspects am dirussed.
