1. A method for setting up a hardware based control system for a hardware based function unit, said function unit being parametrized by a plurality of input variables, said control system including a setting unit and a control unit, said setting unit including at least one regulator, the method comprising: selecting a plurality of value tuples of the plurality of input variables as interpolation points from a parameter space defined by the plurality of input variables; determining an interpolation function that is dependent on at least one control variable and defines a continuous subspace of the parameter space, the subspace having a dimensionality corresponding to a number of the at least one control variables and contains every interpolation point; assigning the at least one control variable to the at least one regulator of the setting unit such that a value of the at least one control variable is stipulated by means of the respective regulator; and storing the interpolation function in the control unit, wherein the interpolation function is determined by, stipulating the subspace inside the parameter space, stipulating, for each dimension of the subspace, a coordinate corresponding to the at least one control variable, and stipulating for each coordinate, a progress function by which each value of the associated at least one control variable is allocated a value of the coordinate.
