A control system is arranged to control the heater system; wherein the control system is programmed to heat the exhaust after treatment system based on a setpoint value. The control system comprises a controller having an error input and an output; that outputs a heating power setpoint value that is adjusted by a feedback signal, said adjusted setpoint value provided in parallel to a branch including the heater system and a branch including a dynamic response system. The dynamic response system comprises a dynamic response part and a delay part. A first subtractor subtracts a measured heat output and an output of the dynamic response system; an adder adds an output of the dynamic response part and an output of the first subtractor. A second subtractor subtracts a heating power setpoint from the output of the adder to provide a control error signal for the error input of the controller.
