✦ Synopsis

Apphcatlons of parameter-adaptive (or self-tuning) &gotal controllers show that there is a need for adaptive PlDcontrol algorithms m practice This contribution presents a new parameter-adaptive PID-controller, which is based on an exphclt combmatton of a two-stage square-root parameter estimator and a numerical controller parameter optimization procedure It can be apphed to a wide range of dynamic processes as well as to the self-tumng of controller parameters during the ~mplementatlon phase, as for continuing adaptive control The adaptwe control algorithms are implemented on a microprocessor-based controller Apphcatmn results are shown for self-tuning control of an air condmoner

## Abstract An evolutionary programming algorithm with a mixed continuous‐discrete parameter representation for application in electromagnetic optimization problems is presented. In our approach, the mutation operator consists of a hybrid combination of Gaussian mutation for the continuous paramete
