Abstract
The invention relates to a control system () for controlling a current source () of an operating device () for lighting means (). The current source () is configured to provide a current (ILM) to the lighting means (). The operating device () comprises a bus interface () electrically connectable to a digital bus () and a voltage supply circuit () for providing a supply voltage (V) to electrically supply the bus interface () and the current source (). The control system () is configured to perform a feedback control of the current (ILM) with regard to a reference current (Iref, Iref), and determine whether a communication via the bus interface () is present or not. Further the control system () is configured to perform a feedforward control of the current (ILM) based on an error (EV) between the supply voltage (V) and a reference voltage (Vref) for the supply voltage (V), by processing the error (Ev) using a first gain (G) in case the control system () determines that the communication is present and a second gain (G) in case the control system () determines that the communication is not present. The first gain (G) is different to the second gain (G).
