PURPOSE AND COVERAM. This book is intended for radio and communi-
cation specialists and students of schools of higher education and
tekhnilcums concerned with the operation of lasers and their application
to the field of communication, The authors made an attempt to-suavari
information on lasers and to explain the ponsibility or using lasers
in communication.

Abstract. It is poanted out that th.aapplication ofocientific methods to
livestock raising contributed in increasing the quantity and
quality of livestock at collective and Soviet farms (Kolkhones and
Sovkhoses) of the Kaz. SSR, The results of such a program were
Bhown at the All-Union Agricultural Exhibition which is described.

it follows that the system must contain a nonlinear
correcting arrangement, with a switching device changing
the sign of the error signal and its derivative during
the transient performance, as required by theIr signs
and correlations. This is realized by the nonlinear
arrangement of the "key" type consisting of t~,.,o
meshes. The diagram of the correcting system is shown
on Fig. 4. This diagram is taken from one of previously
published papers. The first I mesh passes the

PERIODICAL: Avtomatika I telemekhanika, 1960, Vol. 21, Ifoo 8,

TEXT: Firstj it Is noted that the control.lers available at present'shov
discrepancies between technological requirements and control dynamics*
It is therefore necessary to develop such automatic control systems as
guarantoc the necessary quality of control processes for minimum changes
of the controlling actions that are r:quirod for the compensation of dis-
turbances in static modes of operatic (without meaeuremento)o This is
illustrated by some examples* The resulting problem was solved by means
of a now controller developed on the basis of the theory_of non-linear
automatic control systems of varidble structure (Refs* 4 7)e To illus-
trate the "Bynthesis" of the non-linear control law that warrants the
necessary structural change of the oontrollarg the authors studied the

simplest automatic control system which is expressed by non-linear dif-
ferential equations of the second order. This system is schematically
shown in Fig. la. The non-linear control law is "synthesized" for this
system with minimum changes of the controlling action. In order to obtain
this non-linear control lamp the authors employed the method of the
many-sheeted phase surface (Ref. 8). Thuep the problem to be solved is
reduced to the phase representation of a non-linear system, which illue-
trates the successive structural changes. Next, the authors give the three
systems of structures possible for a given structure of the object and in
the absence of other actions in the control law. It is shown that the
equation of a controller warranting the nece 0sary structural change during
the transient must have the form of formula (9). The properties of the
resultant non-linear system are compared with those of the linear control
system that is based on the -130 (1R-130) controller. The maximum
value of the dynamic error Is used for comparisone lormulas (11) and (12)
are written down for the determination of this value for linear and
non-linear systems, respeotively. This comparison indicates thatt contrary

to.linear systems# a rather small error can be obtained for the system
with a non-linear correction, This is due to a quicker action of the
controller, It proved to be suitable to oonstr4ot non-linear controllers
of variable struotareand to exclude the function derived and the
linearizing elements of the switching mechanism. Fig. 3 shows the circuit
diagram and Fig. 4 a photograph of such a controller. The latter consists
of logical. operation circuit with -an integral member of constant velocity.
if this member in combined with six relay ilemontat it warrants the
necessary structural change during the transient* Besides, the controller
has an integral switching toohanism of constant velooitys The controller
deadribed has already been tested industrially, and is at present being
tested in operations Mo So Lodyseva and 06P, Zelentsov aasisted in this
work. It is finally noted that the theorifical atidy of the final
construction of this non-linear controller of variable structure will
be described individually. There are 4 figures and 8 referenoest IA-

TEXT: The authors attempt to synthesize a follow-up system reproduc -
ing without position error any cont-zol action described by conti-
(also transcendental~ functions containing a single integrat-
ing unit and satisfying the condition that, within a wide range of
command functions g(t),'the law'of control remains unchanged. The-
principle of automatic control systems with variable Btructurd is
applied. The control functions g(t) analyzed are of the type g(t)
~P and g(t) =c(tj at which the performance factors of transients re-
main constant. The analysis results in a nonlinear element in the
follow-up system forming the logical function of the control law in
_yarious ways by means of typical logical elements, One possible

TEXT: The author refers to A.M.Letov's demonstation (Avtomatika S
i tolemckhanika, V.18, no.7, 1957) that the quality of an
automatic control system can be improved substantially by change
of sign of the controller velocity at a certain instant of time
chosen so that the generating point in the phas6 space finds
itself on a certain hyperplane, with absence of motion corresponding
to a real positive root. Unfortunately present techpical
possibilities do not permit such systems to be realized and
inexactness in determining the instant of switching leads to
instability. The author seeks a similar system, having the
advantages of conditionally stable systems, without their
disadvantages. It is necessary to select a switching hyperplane

such that it pass through the origin of coordinates, be
suffic,iontly close to the Letov hyperplane and with the phase
velocity vectors in its vicinity everywhere directed towards it.
Then the generating point will move in slipping mode on the
hyperplane and-with small deviations away from it will always
return 'to it. In such cases the quality of transient processes
will be almost that of the conditionally stable system without the
need for exact incidence of the generating point on the hyperplano.
The author considers successively stability over the entire
hyperplano and the conditions of incidence on the hyperplane for
arbitrary initial conditions.
