STABILITY OF SYSTEMS, WITH PERIODICALLY VARYING PARAMETERS

Abstract

Tho va ~iabZo parar eto systome and networks have boon an lyaad th.ouch the tochniquoa of getting solutions of linear diffo o - tial. ar atinno z,ith periodics coofficionts, The variable invosi. tiga od in most of the cases has boon tlme Nowevax, tho analysis Iso boon so for approximatee and the solutions obtained are in nest of the cocoa4problom-orionted*' o. flathiauOo Equation, 11ul°a Equation etc. This roouited duo to the tendency of reducing the system study to the conventional second order equations foxulation Very often it is necessary to find the infomation regarding tho stability of aystne and then to suggest appropriate rneasv r:e.s , to affect and ensure such stability, the problem is difficult for practical cases bocau of
