REGELSYSTEM FÜR EINE GLASFORMMASCHINE

摘要

A control system, more especially for use in a glassware forming machine, to control movement of a driven member (12), for example carrying molten glass, between first and second rest positions, wherein the member is driven via a pneumatic valve (16) which receives control signals from a signal processing system (32) which continually receives feedback representing the position of the driven member, and responsibly thereto the control signals are produced in accordance with a repetitive algorithm determining a motion profile controlling both velocity and acceleration in such a manner that the driven member is brought to rest exactly at the required position without exceeding limiting values for acceleration.
