Description

Verfahren zur Vorgabe der digitalen Sollwerte bei kombinierten analogdigitalen Mehrfachregelungen . Die Erfindung bezieht sich auf ein Verfahren zur Vorgabe der digitalen Sdllwerte bei kombinierten analog-d:K.gitalen Mehrfachregelungen.Procedure for specifying the digital setpoints in the case of combined analog-digital Multiple regulations. The invention relates to a method for specifying the digital target values with combined analog-d: K. digital multiple controls.

Bei kom4nierten anaiog-digitalen Mehrfachregelungen, z.B. bei Drehzahlregelungen für Papiermaschinen, ist es bekannt, die analog-digit-ale Soslwertvorgabe zu koppeln. So werden beispielsweise Potentometer und Wimkelcodiersr bzw. digitale Potentiometer und digital codierte Schalter mechanisch gekoppelt' Nachteilig bei einer derartigen Sollwertvorgabe ist jedoch, da8 eine stoßfreie Sollwortverstellung nicht möglich@ist. Weiterhin unterliegen mechanisch bewegte Teile einem: Verschleiß, so da8 die Betriebssicherheit vermindert wird.With combined analog-digital multiple controls, e.g. for speed controls for paper machines, it is known to couple the analog-digit-ale setpoint specification. For example, potentometers and Wimkelcodiersr or digital potentiometers are used and digitally coded switches mechanically coupled 'disadvantage of such Setpoint specification is, however, because bumpless setpoint adjustment is not possible @. Furthermore, mechanically moving parts are subject to: Wear, so that operational safety is decreased.

Aufgabe der vorliegenden Erfindung ist es dechal6, die vorgenannten Nachteile bei einem Verfahren zur Vorgab® der digitalen Sollwerte bei kombinierten analog-,digitalen Mehrfachregelungen., bei dem den einzelnen Regelkreisen die analogen Sollwerte in Form von Spannungen, die an Poteutiometern abgegriffen werden, vorgegeben sind und zur Vorgabe der digitalen Solliierte jedem Regelkreis ein von einer leitfrequent gespeister 'Frequenzmulti«. plikator zugeordnet ist, zu vermeiden. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die den analogen Sollwerten entsprechenden Potentiometerepannungen in eünem allen Regelkreisen gemeinsamen ..SD-Wandler in Digitalwerte umgeformt und .zur Einstellung des Kultiplf"kationsfaktors der ]'requenzmulti=-plikatoren dienenden Speichern zugeführt werden, 'wobei die Zuordnung der für die einzelnen Regelkreise geltenden umgeformten Sollwerte au den jeweiligen Speichern durch ein .allen Regelkreisen gemeinsames Steuerwerk erfolgt. Die Erfindung wird nachstehend an Hand. eines in `der Figur dargestellten Blockschaltbildes näher erläutert.The object of the present invention is to address the aforementioned disadvantages in a method for specifying the digital setpoints in combined analog and digital multiple controls, in which the analog setpoints are given to the individual control loops in the form of voltages that are tapped off at potentiometers and for specifying the digital target values for each control loop, a 'frequency multi' fed by a master frequency. is assigned to avoid. According to the invention, this object is achieved in that the potentiometer voltages corresponding to the analog setpoints are converted into digital values in an SD converter common to all control loops and fed to the memories serving to set the culture multiplication factor, " The assignment of the transformed setpoints applicable to the individual control loops to the respective memories is carried out by a control unit common to all control loops. The invention is explained in more detail below with reference to a block diagram shown in the figure.

In der Figur sind mit 10, 20 und 30 f349 einzelnen Regler einer Mehrfachreglung bezeichnet.

Die den Potentiometeratellungea entsprechenden Soll-. ®pwnungen rierden nacheinander über Schalter 14,"'"24 und 34 an den Einging die A/D-Wa"adlere 2 gelegt und. döx°t in Digitalwerte umgeformt. Diese Digitalwerte Norden ih die den einzelnen Regelkreisen zugeordneten entsprechenden Speicher 11 oder 21 oder 31 eingegeben und dienen zur Einstellung dee Hultiplikkationsfaktorä der nachgeschalteten lrrequensnultiplikatoren 12, 22 und 32.Die Zuordnung der für die einzelnen Segelkreise geltenden umgeformten analogen Sollwerte zu'«ea'Jeweiligen Speichern l1* oder 2't oder 31 erfolgt durch das Steuerverk 3, das über die strichpunktiert gezeichneten Wirklinien 4 und 5 die Schalter °14, 24 und 34 sowie die zugehörigen Speicher 11" 2'1 und 31 --aueteuert . -In the figure, 10, 20 and 30 f349 denote individual controllers of a multiple controller.
