A HYBRID AALOG-DIGITAL PARAMETER OPTIMIZER FOR ASTRAC II,

Abstract

A new automatic multi-parameter optimizer for iterative differential analyzers employs sequential random parameter perturbation. The nominal parameter poant changes whenever the random perturbations inprove the system performance measure. Binary counters operate simple digital-to-analog converters to implement parameter storage, multiplication, and step-size changes. All-digital logic yields different types of random perturbations, viz. simple random walk, random walk with reflecting or absorbing barriers, and various types of correlation over successive perturbations.
