TEXT: An aaalysis is, given of the 1-atexinittent operation
of a relay controlling slow procer-ses, the arrangement of which is
shown in Fig. 11 The object of its control K, is an aperiodic, link
of the :'-irst order witli a Lime constant T, for regulating the
para-
meter 6. The control organ CO is actuateg'by an executive organ EO
having a constant speed of rotation. The regulator consists of a
relay ataplifier P and measuring 11~~ridge 11. The chopper C
switches
in the regulator periodicalLy. The -author formulates initial equa-
tions, cormidering the chopper as closed, and assuming that the
