Method of Algorithmic Correction of Dynamic Properties of Special-Purpose Electric Drive

The technique of digital algorithmic correction of dynamic properties of the electric drive is offered. The application of the technique allowed achieving quasi-invariant properties of the electric drive in relation to the angular velocity of its rotor. The method allows synthesizing three digital algorithms: proportional-differential regulator; regulator with correction drive modal dynamic properties; algorithmic meter of angular speed of electric drive rotor. The joint use of these three algorithms allows to reduce the mean-square error of tracking the optimal law of motion by nearly 4 times and to reduce the influence of shock (impulse) disturbances by 3 times. Thus, it becomes reasonable and possible for practical implementation to use only an algorithmic method of improving the dynamic properties of electric drive, which does not require the use of additional equipment.
