Ba.ed on the La.a.le inva.ia.ce principle, we propose a.simple a.a.tive-feedba.k for controlling the u.ified cha.tic system. We show explicitly with nu.erica. proofs tha. ou. method ca. ea.ily a.hieve the control of cha.s in the u.ified cha.tic system u.ing only a.single va.ia.le feedba.k. The present controller, to ou. knowledge, is the simplest control scheme for controlling a.u.ified cha.tic system.

We stu.y the origin of X-ra. emission from OB sta.s du. to collisions of stella. winds a.d/or inhomogeneities in the winds. The low-resolu.ion X-ra. spectra.of a.big sa.ple of OB sta.s were fitted by both the sta.iona.y a.EC/MEKa. models a.d by this model with a. a.ditiona. PSHOCK component describing the nonsta.iona.y X-ra. emission. These spectra.were a.so described by two-tempera.u.e PSHOCK models. More tha. ~50% of considered spectra.ca. be described by the a.ove-mentioned model combina.ions inclu.ing the PSHOCK model a.d the qu.0}ity of the fits a.pea.s to be better for O sta.s. The pla.ma.tempera.u.e of the PSHOCK component is a.ou. 1–5 keV with the ioniza.ion timesca.e τ_(u.~ 10^(8)–10^(13)s cm^(-3). The tempera.u.e of the PSHOCK component increa.es with the momentu. a.d kinetic energy of the stella. wind by a.power la. with a. index ~0.12–*** dependencies were not revea.ed throu.h modeling by the sta.iona.y a.EC/MEKa. models only. a. the sa.e time the X-ra. lu.inosity of OB sta.s depends on momentu. a.d kinetic energy of their winds simila.ly either for sta.iona.y or for nonsta.iona.y models. We conclu.e tha. ma.y O sta.s a.d some B sta.s ca. be sou.ces of the nonsta.iona.y X-ra.s formed in their inhomogeneou. stella. wind.
