METHOD FOR SUPPRESSION OF LOW-FREQUENCY OSCILLATIONS IN TRANSPORT MACHINE TRANSMISSION

摘要

FIELD: machine building.;SUBSTANCE: invention relates to a method for suppression of low-frequency oscillations in transport machine transmission at the stage after kinematic levelling of driving and driven parts speeds. Method consists in creation of antiphase control action on own frequency of dynamic system corresponding to lower single-node form of oscillations. Novelty consists in synthesis of regulator based on calculation of parameters of redistribution in time of control function in accordance with algorithms ZV (Zero Vibration), ZVD (Zero Vibration and Derivative), ZVDD (Zero Vibration and Double Derivative), RAMP and so forth. Amplitude and duration of stages of control function (control torque), as well as the beginning of the algorithm action are determined by initial conditions of oscillatory process of dynamic system, which are identified by signatures of the first and second derivatives of torque. Type of Shaper-filter is determined on the basis of selection of priority parameter, which characterizes quality of transient process - overshooting, quick action or robustness.;EFFECT: higher operational properties of transport vehicles, such as acceleration intensity, level of comfort.;1 cl, 6 dwg
