Abstract

The inventive control arrangement comprises a feedback controller, in an iterative learning controller (1 ), and a delay controller (16). The feedback controller drives EHVA system. The EHVA systems means in this context the system needed to drive one valve or the system driving several valves. For simplicity, it is easier and more understandable to think about the driving of one valve. It is clear that the drive of one valve is expandable to the system driving several valves
