The identification of time delay in the linear plant is one of the important tasks. It is especially hard problem when the plant is non-stationary. New possibility in this field is opened by application of an evolutionary algorithm. The method of identification proposed in the paper is based on three classes of input signals. In the first case we can obtain and operate on the whole unit step re...

In this paper the performance of the MMSE-based equalization receivers under overloading conditions is analyzed, for SISO (Single Input, Single Output) and MISO (Multiple Input, Single Output) antenna arrangements. Both random and orthogonal spreading sequences are analyzed, for the main UMTS (Universal Mobile Telecommunications System) TDL (Tapped Delay Line) channel models, namely Pedestrian ...

A design method for a feedback controller with integrated delay-based command shaper is presented in this paper, based on the Smith predictor concept. PosiCast and related input command shapers (ZV, ZVD, EI etc.) are primarily intended as feedforward filters for reference (set point) signals. Nevertheless, due to their superior effectiveness in suppressing vibrations, there is a good motivation...

In this paper we present methods for generating bounds on interconnection delays in a combinational network having specified timing requirements at its input and output terminals. An automatic placement program which uses wirability as its primary objective could use these delay bounds to generate length or capacitance bounds for interconnection nets as secondary objectives. Thus, unlike previo...

In this paper the concept of multiple models and concept of switching controllers is used. The analog part of the system is described by finite set of continuous-time models with input delays. The continuous-time models include unmodeled dynamics in the form of affine matrix family. Using suitable transformation the models with input delay is converted in the delay free models. Then for multipl...

The stabilization by feedback control of systems with input delays may be considered in various frameworks; a very popular is the abstract one, based on the inclusion of such systems in the Pritchard-Salamon class. In this paper we consider the elementary approach based on variants of the Smith predictor, make a system theoretic analysis of the compensator and suggest a computer control impleme...
