Simulace napájení pro stejnosměrné motory

Abstract

This bachelor's thesis focuses on the comparison and analysis of DC motor power supply options. For the actual implementation of the simulations, DC motor power supply using pulse converters is chosen. Simulations are performed on multiple simulation models. From the basic model with ideal blocks, through the subsequent removal of simplifying assumptions or the use of other approaches. For comparison, we have the initial drive model from the Matlab Simscape environment. For models for simulating bipolar and unipolar control, we used an H-bridge connection. On individual models, we compare the output waveforms for voltage, current and speed. Subsequently, on models with a connected gearbox, inertia and torque, we determine how individual types of loads or mechanical couplings of the motor behave and what the differences are between them. The result is a mutual comparison of individual models.
