Abstract: FIELD: mechanical engineering; applied electromechanics. 
     SUBSTANCE: invention relates to devices for supporting rotating parts in suspended condition.  Proposed method of discrete control of electromagnetic bearing comes to the following: value of voltage supplied to coils with control windings is chosen, fact of passing of support necks of rotor through fixed level of deflection relative to axis of stator is determined and voltage from coils with control windings is either removed or applied.  When selecting inductivity of coils, rotor is lifted until stopping of current rise in coils with control windings.  Then m fixed levels of deviation from zero, 2 m values of velocities of rotor necks, movement of 2m threshold values of current differences in diametrically opposite coils with control windings are chosen and set.  At equal lapse of time, currents in all coils are determined, as well as all deviations from zero level and velocities of movement of rotor necks at change over of rotor through one of m levels.  Control actions onto actuating device are formed which, according to values of control actions simultaneously feeds or removes voltage from all coils with control windings. 
     EFFECT: increased response, enlarged stability range of automatic control system.

Abstract: Изобретение относится к области машиностроения, а именно к системам управления торможением для транспортных средств. Тормозящий момент сравнивается с заранее определенным пороговым тормозным моментом. Сигналы погрешности вектора скорости колеса также формируются для указания разницы между вектором скорости колеса и опорным сигналом вектора скорости. Модулятор-интегратор смещения крутящего момента, отвечающий на сигналы тормозного момента, регулирует сигналы погрешности вектора скорости колеса для создания сигнала контроля противоскольжения. Интегратор-модулятор смещения крутящего момента также можно инициализировать до величины измеренного тормозного момента, когда сигналы погрешности вектора скорости колеса указывают на начало скольжения. Сигналы разницы тормозного момента формируются для указания разницы между тормозным моментом и управляемым тормозным моментом, а отрегулированный сигнал погрешности тормозного момента формируется в зависимости от сигналов разности тормозящих моментов. Достигается предотвращение глубокого начального скольжения, что способствует быстрому и контролируемому применению тормоза. 4 з.п. ф-лы, 3 ил.

Abstract: FIELD: agriculture. 
     SUBSTANCE: method comprises modeling the process of interaction of the water flow with rough surface by changing the working section of a sloping channel with rough surface to be studied for the smooth surface, determining dependence of height of flow on the water flow rate for the smooth surface.  The specimen with the smooth surface is changed for the specimen with rough surface to be studied, and the dependence of the flow height on the water flow rate is determined for the rough surface.  The coefficient of the wetted perimeter is determined by dividing the critical flow rate of water corresponding to the critical Reynolds number at the boundary between the laminar and transient regimes of water flow for the rough channel surface by that of the smooth channel surfaces.  The value of wetted periphery for the rough surface is assumed to be the production of the coefficient of wetted perimeter by the wetted perimeter for smooth surface.
