Description

Изобретение относитс  к области электрического и злектрогидравличбского след щего привода и может быть использоваиа, но в системах автоматического регулировани  с люфтом и упругими дефор.ма.ци ми ,в механической передаче, охваченной главной обратной св зью. Известен способ получени  сигнала дл  стабилизации след щего привода, основанный на дифференцировании сигнала, пропорционального скорости исполнительного двигател . Известный способ не обеспечивает необходимой точности стабилизации след щего привода . Согласно изобретению дл  -повышени  точности стабилизации след щего привода сигнал , протюрциональный моменту, развиваемому исполнительным двигателем, интелрируют и сравнивают его с продифференцированным сигналом, пропорциональным скорости .исполнительного двигател , а получе«ную (разность интегрируют.

В качестве датчика скорости исполнительного двигател  в электрическом и электрогидравлическом приводе может быть использован тахогенератор, жестко св занный с валом исполнительного двигател . Сигнал, снимаемый с датчика момента, разРазность полученных сигналов лс (О Пс 0) - дм (О ky W (р) ITj p -- дс в (О (9) 1 + реооразуют интегрирующим контуром с пеедаточной функцией () осле чего получают напр жение 7 .The invention relates to the field of electrical and electrolytic follower drives and can be used, but in automatic control systems with backlash and elastic deformations, in a mechanical transmission covered by main feedback. A known method of obtaining a signal for stabilizing a servo drive is based on differentiating a signal proportional to the speed of the executive engine. The known method does not provide the necessary accuracy of stabilization of the following drive. According to the invention, in order to increase the accuracy of stabilization of the follower drive, a signal projective to the moment developed by the executive engine is integrated and compared with a differentiated signal proportional to the speed of the executive engine, and received (the difference is integrated. This method is implemented as follows. Signal removed from the speed sensor of the executive engine. Ude (): zh k py. (t) k ,, (i) +. ± .f (Q is the comfort of differentiation, by its contour with the primary function kc (p) r-o, it turns out c ((p) 0 (0 + kц, (+ Tnp)) (( ), (3) + JH (I +% P) (C is the steepness of the signal of the speed sensor of the executive engine; t is the gear ratio of the mechanical transmission (); is the time constant associated with the presence of losses in the elastic element of the mechanical transmission; D is the loss coefficient for viscous friction in the elastic element of the mechanical transmission; C is the stiffness coefficient of the elastic element for the mechanical transmission; n is the moment of inertia of the object;) is a nonlinear function (with deadband) of the moment transfer depending on the angular positions 0 (0 where hell () - angle of rotation of actuator about the engine; a (t) is the angle of rotation of the object. The tachogenerator, which is rigidly connected to the shaft of the executive engine, can be used as the speed sensor of the executive engine in an electric and electro-hydraulic drive. The signal taken from the torque sensor, the difference of the received signals LS (O Ps 0) - dm (O ky W (p) ITj p - ds in (O (9) 1 + re-integrate the integrating circuit with the pedal function ()) then get Life 7.
