Abstract
A control system for injection molding machines comprises a memory means (16) for storing set values. Further, a signal input for the transmission of actual values to the control system is provided. A first control means (18) is used for the transmission of a control field with consideration to previous values. A second control means (20) is provided for the transmission of a correction value, in particular with consideration to a deviation of the actual value from the set value. A correlation means (22) serves to correlate the control field values with the correction value for outputting a control variable.
Claims15
A control system for injection molding machines, especially for speed and/or position control, comprising
- a memory means (16) for storing set values,
- a signal input for the transmission of actual values to the control system,
- a first control means (18) for the transmission of a control field with consideration to previous values,
- a second control means (20) for the transmission of a correction value, and
- a correlation means (22) for the correlation of the control field values with the correction value for outputting a control variable.
A control method for an injection molding machine, wherein
- set values and actual values are determined,
- a control field is determined with consideration to previous values,
- a correction value is determined, and
- the control field value is correlated with the correction value for outputting a control variable.
