In a controller, having a control input, for controlling a system to a desired output, the system having a time dependent system output, a controller operation based on a polynomial function having an order, a plurality of control coefficients and a corresponding plurality of polynomial terms, a method for tuning the controller, the method comprising: a) calculating a value for each of the plurality of control coefficients by fitting the polynomial function to a plurality of control transfer characteristic data; b) multiplying the values of the control coefficients by a scaling value; c) computing an output error signal based on a difference between the time dependent system output and the desired output; and d) tuning the scaling value using a descent-based optimization method to reduce the output error signal; e) comparing the output error signal to an error threshold; and f) increasing the order of the polynomial function based on the comparison between the output error signal and the error threshold by adding at least one new polynomial term and a corresponding at least one new control coefficient.
