Electric Circuits U ~ ) 791 frequency methods for studying t:~,ansient cuad stleady-stlate conditions in such circuits. A synchronous mac-l-Lirie -".-heory based on frequency methods is discussed and is extended z--o a ganerall case of unsymmetri- cal conditions. Ac~--ozrding to the aut-hor, the problem of investi- gating t.-ansients in synehrz,)n,.)us machines under asymmetrical con- ditions remains largely li-nzolved. The author quotes professor A. A. Gorev, who in a racent-ly publ-4shed monograph on transients In synchronous machines wi-ita that in t-1-ze case of unsymmetrical oondi. tions, equations, which in the gen-arall case contained periodic coefficients, become irveducible and -t-heir solution complicated to the extent that they have no practical appl-loation. The autphor applies frequency methods based on a Fo-a::rier expansion and presents general methods of invest-igation. These methods are, according to thq author, directly applicable t-~ the altudy of symmeteloal as well as unsymmetrical conditions of synchronous machine operation, Practical applicattion of these methods is based on the use of an a-c calculating board and t1he metChod of symmetrical components,, and does not necessitate the introduction of any methods not com- mon to everyday electzt-cal engineering practice. The monograph also examines problems conxiected with the physical natu--e of resonanae phenomena under paramaturicall resonant conditions.

SOV/4955 6ystems, partl,-:ularly in systems of automatic control. He investigates the problem of using frequency response methods for the stabililty analysis of such systems. In an earlier work the author discussed an attempted approximate solution of the stability problem based on the assumption that a linear compcnent with properties of an ideal filter has been included in the system under investigation. He con- siders. this approach as unsatisfactory and presents In this monograph an accurate method of solving the problem without assuming the inclusion of an ideal filter. This solution consl5t5 In the reduction to a finite form of the characteristic equation of the family of equattions with periodically changin coefficients, expressed in the form of an infinite (Hilli determinant. The author uses the same method as the one employed for the deduction of the Hill equation. The results obtained can be used in solv- Ing several technical problems connected with the investi- gation of networks with variable parameters. When the ob- ject under -.ontrol appears to be a system with variable Card-771--T Problems In the Theory (Cont.) SOV/4955 parameters, it becomes difficult to apply the usual method of system analysis and synthesis, namely the method of the z- transform. The d1ff1culty 15 connected with the necessity of knowing the reaction of the network to the applied dis- turbance, in other words, the L-transform of this reaction. In particular, for systems with periodically or exponentially changing parameters, the L-transform of thIs reactlon may be expressed with infinite determinants. Such complex ex- pressions do not give a direct possibility of passing over to the z-transform. In the present work the author suggests a method which permits the passing over from the L-trans- form of the above indicated reaction to the ftn1te trans- cendental functions of the operator p, which makes it possi- ble to reduce the theory of networks with periodical para- meters to a form analogous to the theory of long lines. Obtained relationships make it possible to pass over to the z-transforms and it then becomes possible to expand the z-transform methods to systems with variable parameters.
