    Adaptacyjny układ regulacji z predyktorem Smitha z możliwością zastosowania w systemach rozproszonych
    (Wydawnictwa AGH, 2008) Tutaj, Andrzej
    The paper describes an adaptive control system for a linear finite-dimensional and asymptotically stable SISO plant with a slowly changing delay time at the input or output. The estimate of a dead time obtained by a continuous identification is used in a delay line, which is a part of a Smith predictor. Use of the adaptation enlarges the stability region and increases the performance of a system. The described setup can be used for distributed control systems where delays are introduced by the communication network. This approach succeeds if delays in the network vary slowly with time.

    Realizacja predyktora Smitha na platformie sprzętowo-programowej »soft PLC« bazującej na komputerze klasy PC
    (Wydawnictwa AGH, 2006) Oprzędkiewicz, Krzysztof
    In the paper problems of practical implementation a special control algorithm »Smith's predictor« were presented. The control system was implemented onto PC - based »soft PLC« platform. A basis version of »soft PLC« system (without real-time kernel) was used. In the paper the hardware and software platform to the task realization were shown, results of experimental tests of real-time requirement during considered control algorithm are also presented. The main conclusion from the paper is that the tested »soft PLC« system implemented with basic version of software assures keeping the longest cycle time of a controller fully responsible for a wide class of industrial control tasks.

    Zastosowanie zmodyfikowanych wersji predyktora Smitha w rozproszonych układach regulacji
    (Wydawnictwa AGH, 2005) Tutaj, Andrzej
    This paper deals with modifications of the Smith predictor used in the distributed control systems. Presented modifications make predictor handle the variable time delays or the packet dropout. The paper describes several types of modifications together with the specifications of network properties for which the modifications are suitable. For some of presented systems the results of simulations are included. Based on this results the quality of control for classical and modifying predictors is compared. The issue of stability is also addressed.
