Control method of residual deviation (residual deviation) generated in elevator driving control

摘要

The present invention relates to a method for controlling a residual deviation generated in an elevator drive control, and a method of the present invention is a elevator drive control device for judging whether an elevator is stopped or in operation, And if it is in operation, performing a seventh step; A second step of initializing K = 0 if it is stopped; A third step of inputting an output signal Iz of the amplifier to the second current command circuit when K = 0; A fourth step of performing a finite impulse response (FIR) filter operation when the signal Iz is input to the second current command circuit; A fifth step of performing a fifth step if K? N-1 and a fifth step of feeding back to a third step if K? N-1; And outputs Iofs [nTn] (Idfs [nTn-1] + Iz [nTn]) if K? N-1; And a seventh step of maintaining the output Iofs value. The present invention having such a configuration is characterized in that it can compensate for the residual deviation more precisely by using an algorithm to which a digitalized FIR filter is applied.
