Abstract

CONTROL OF TIME DELAY INTEGRATING SYSTEMS IS A CHALLENGING AND ON-GOING RESEARCH. IN THIS PAPER A NEW STRUCTURE FOR CONTROL OF STABLE AND INTEGRATING TIME DELAY SYSTEMS IS PRESENTED. THE CONTROL DESIGN PROCESS IS AS SIMPLE AS SELECTION OF SOME CONSTANT GAINS, FOR WHICH SIMPLE FORMULAE ARE INTRODUCED. THE DESIGN METHODS ARE DERIVED ANALYTICALLY, WHILE NO FRACTIONAL APPROXIMATION FOR THE TIME DELAY TERM OF THE PLANT TRANSFER FUNCTION IS USED. SIMULATION, AS WELL AS, EXPERIMENTAL STUDIES REVEAL THE EXCEPTIONAL EFFECTIVENESS OF THE PROPOSED METHODS IN ACHIEVING A ROBUST AND WELL-PERFORMING TRACKING, EVEN WHEN THE PLANT PURE TIME DELAY IS VERY LARGE.
