Final report

  
Results in Hungarian
A változó struktúrájú rendszerek témában az egyik kutatási eredmény e rendszerek stabilitására vonatkozik. A fix pontjhoz tartozó Poincaré térkép függvény Jakobi mátrixának a sajátértékeit alkalmazza és grafikus támogatással szemléletesebbé, egyszerűbbé teszi a számitást Kihasználja a struktúra sorozat periodicitását, ezzel átláthatóbb, gyorsabb eljárást ad a Jakobi mátrix meghatározására. Az állapotváltozók különbségét használja a Poincaré térkép függvény deriváltjai helyett és minden lépéshez geometriai interpretációt ad. A kulcs elem az úgynevezett virtuális állapotvektor bevezetése, igy mindig ugyanazokkal a kapcsolási időpontokkal lehet számolni. A módszert több rendszeren alkalmaztuk. Vizsgáltuk a közvetlen nyomaték-szabályozású hajtást. Bifurkációs diagragramot, Lyapunov exponenst és return térképeket számoltunk. Periódikus, szubharmonikus, kaotikus és intermittens állapotokat mutattunk ki. A megújuló és a hulladék-energiaforrások témákban a napenergia és a nyomáscsökkentésből visszanyerhető, 100-200 ezer fordulat/perc gépegységet igénylő energia hasznosítás területeken értünk el eredményeket. Kidolgoztunk egy angol nyelvű multimédiás programcsomagot, amely a nemlineáris dinamikus rendszerek elméleti alapjainak a Ph.D szintű tanítására és tanulására szolgál. 44 tudományos cikket jelentettünk meg: 7 folyóirat (4 angol)- többi konferencia (mind angol)-cikk. A konferenciákon kívül Amerikában, Ázsiában és Európában 19 előadást tartottunk.
Results in English
One of the research results in the topic of the variable structure systems is related to a new approach for the determination of the stability of such systems. It applies the eigenvalues of the Jacobian matrix of the Poincaré map function belonging to a fixed point making the computation simpler and transparent by graphical support. In addition it provides a faster approach for the determination of the Jacobian matrix. It uses the difference of the state variables in place of the derivative of the Poincare map function and yields geometric interpretation to each step. The key element is the introduction of the so called virtual state vector. It ensures that always the same switching time can be used within each period. The method was applied for more systems. The drive with direct torque control was analysed. Bifurcation diagram, Lyapunov exponent and Return map were calculated. Periodic subharmonic, chaotic and intermittent states were detected. Results were achieved in the subject of renewable and waste energy recovery. More closely the subjects were solar energy and energy recovered from pressure reduction in steam and/or gas pipe line where a rotating machine set with 100-200 thousand rpm is needed. A multimedia program was worked out in English for teaching and learning on Ph.D level the basics of the theory of nonlinear dynamics. 44 scientific papers were published: 7 Journal (4 English)- 37 Conference Proceedings ( all English) papers. Beside the Conference presentations 19 lectures were delivered in America, Asia and Europe.
