A control system, a method of operating the same, and a method for setting up the same are disclosed for simplified driving of a function unit parametrized by a plurality of input variables. The control system includes a setting unit and a control unit, the setting unit being used to set a number of prescribed control parameters and to feed them to the control unit. A value tuple that is fed to the function unit for the parametrization thereof is determined by the control unit as a function of the controlled variables in accordance with a stored interpolation function based on interpolation points. To set up the control system, it is provided to select a number of value tuples of the input variables as interpolation points from a parameter space defined by the input variables, and to determine the interpolation function in such a way that it defines a continuous subspace of the parameter space which has a dimensionality corresponding to the number of controlled variables and contains every interpolation point.
