The present invention relates to a control unit (6) for controlling a system comprising one or more devices (1a‐b, 2a‐b, 3), each device having at least one control loop (4a‐f) for controlling the device based on a set point value (S1 – S5). The control 5 unit is adapted to receive measured values of system parameters of the system. The control unit comprises a simulator unit (8) configured to run simulations of the system based on a model of at least a part of the system, and to repeatedly during operation of the system predict the state of the system at a future point in time based on the received measured values of system parameters and current set 10 point values of the devices, and a control part (9) configured to determine new set point values for the devices based on the predicted the state of the system at said future point in time.
