Regelungsstruktur für eine Klasse von Förder- und bearbeitungsprozessen und anwendung in der postautomatisierung

The feeding rate of items or bulk goods to a transport and processing system in many cases requires a careful setting in order to take advantage of the full processing capacity and to not overload the process. The corresponding control task occurs for example in the field of automated manufacturing - in the application of the author the processing of mail items in an automatic address reading machine is concerned. In this contribution a special control structure is presented, which has some optimality properties and which has proven to be well suitable in practice. At the same time questions arise which may motivate to further investigate the considered class of systems with varying delay.
