    Development of mathematical model of controlled plant using the obtained experimental data
    (Lviv Polytechnic Publishing House, 2016) Fedoryshyn, Roman; Klos, Sviatoslav; Savytskyi, Volodymyr; Lviv Polytechnic National University
    The results of the experimental study of the dynamical and static properties of an electric oven as a controlled plant are presented in the paper. Up-to-date microprocessor instruments were applied during the experiments. Mathematical model of the electric oven was developed on the basis of the experimental data. The adequacy of the model was verified.

    Analysis of pulse-width modulation methods
    (Видавництво Львівської політехніки, 2017-12-23) Fedoryshyn, Roman; Klos, Sviatoslav; Lviv Polytechnic National University
    The purpose of this work is to present the results of analysis of pulse-width modulation methods, i.e. PWM based on the sawtooth waveform generator and PWM based on an integrator and a switch element. Mathematical formulae for designing the tuning parameters of PWM diagrams are presented. An example of PWM application for controlling a thermal plant is presented.
