Abstract

Combined control patterns corresponding to the actual control coordinates point (px) are formed by morphing a shape of the model control patterns PA, PB, PC having J pieces and corresponding to each morphing coordinates (pa, pb, pc), in the control pattern space CPS extended by the second type of input variable β and the output variable α. The morphing is performed according to weight between the morphing coordinates (pa, pb, pc) in the M-dimensional input space MPS and the actual control coordinates point (px). Combined control patterns Px are formed, and output variable value a corresponding to the input value (px) based on the combined control pattern Px is calculated.
