Abstract
An apparatus for regulating an injection moulding machine comprising a crank lever mechanism for moving the movable mould mounting plate, wherein the crosshead of the crank lever mechanism is driven by a drive device. The regulating apparatus is constructed as a cascade regulator, wherein the follower regulating circuit (inner regulating circuit ()) is a force regulator which compares a force reference value (F) supplied by a guide regulating circuit to a force actual value (F) detected by a force measuring device () at the drive device () and outputs a control parameter or parameters to the drive device (), and wherein the guide regulating circuit (outer regulating circuit ()) is a trajectory follower regulator which in dependence on a stored or generated reference trajectory (x,{dot over (x)},{umlaut over (x)}) for the crosshead ascertains and outputs on the one hand a travel and/or speed actual value (x,{dot over (x)}C) detected by a travel measuring device () at the crosshead () and on the other hand the force reference value (F) for the follower regulating circuit.
