Abstract:
In a control system requiring training of a multivariable power series to learn a desired function, said control system having signal inputs and generating control signal outputs for controlling an apparatus, said power series being fully defined by parameters used in said power series, order of polynomial with each input variable, and number of input variables, said power series yielding an output of a change variable in response to an array of change variables inputted to said power series, said change variable consisting of a level variable and a change of level variable, where a change output is the change of level variable component of said change variable outputted by said power series, a method for obtaining said change output for use in modifying power series parameters to learn said desired function, said method comprising:establishing such a change variable for each input to said power series, each said change variable inputted to said power series related to two data points, wherein each said data point is characterized by an array of input values and a desired output value; and calculating said change output directly from said change variables inputted to said power series; and using said change output for adjustment of parameters of said power series for use in generating said control signal outputs.
