    Identifikace vícerozměrných soustav
    (Technická Univerzita v Liberci, 2008) Vydra, Jan; Olehla, Miroslav
    The content of this work is a description of the basic methods and models to identify the multivariable systems. It describes the direct and indirect identifying methods. Will be demonstrated, how the external model can be obtained from the state model as well as these relationships can be directly derived from the state description in the form of transfer matrix, or matrix fractions. Subspace methods will be mentioned as well. In conclusion, we'll introduce the recursive identification methods ARX, ARMAX and OE.

    Laboratorní model řízení točivého zdroje elektrického proudu
    (Technická Univerzita v Liberci, 2006) Štěpánek, Petr; Olehla, Miroslav
    The diploma thesis deals with proposal and realization of a laboratory model of control of a DC generator. A synchronous motor drives a shunt-wound dynamo, which has constant actuating. The aim of the control is to keep constant voltage at output of the dynamo under changing load. A programmable controller PLC Simatic S7-300 by Siemens was used as a control unit, to which a control algorithm for regulation of dynamo voltage in STEP7 environment has been programmed. Its output is the required value of speed, which is entered as voltage in a speed cycle of the control module. The diploma thesis is accompanied by a simulation model developed in Matlab Simulink.
