And the driving portion in current injection is calculated according to the actual value of controlled quentity controlled variable of the movable part and the deviation of setting value
The setting value of operating quantity,
The operating quantity of the driving portion in the current injection is, the actual value of the controlled quentity controlled variable of the movable part and setting value
Deviation is multiplied by the time integral value of the value of storage gain, the reality with the controlled quentity controlled variable based on the movable part in the previous injection
The sum of setting value of operating quantity that the deviation of actual value and setting value calculates.
2. injection (mo(u)lding) machine according to claim 1, wherein,
The control device controls the driving portion, so that the actual value of the operating quantity of the driving portion becomes setting value.
