Abstract:
A method of controlling a process having dead time is disclosed. This method obtains input evaluating criteria for setting values of process response outputs in relation to known input information, the input evaluating criteria being represented in one or more of the integral, proportional and differential type process responses. Fuzzy inference is used to estimate a variation in the process response output occurring upon lapse of a dead time or a control amount relating thereto on the basis of the value of an input evaluating criterion. The process is subjected to fuzzy PI (proportional and integral) control based on the estimated value.

Abstract:
In a method for constructing an acoustic transfer function table for virtual sound localization, acoustic transfer functions are measured at both ears for a large number of subjects for each sound source position and subjected to principal components analysis, and that one of the transfer functions which corresponds to a weighting vector closest to the centroid of weighting vectors obtained for each sound source position and each ear are determined as a representative.
