Simulacija stikalnega pretvornika napetosti z regulatorjem

PRESKAR, ELVIS (author), Trost, Andrej (mentor)

Diplomsko delo opisuje regulacijo napetosti stikalnega pretvornika navzdol z uporabo PID regulatorja. Vse simulacije so izvedene v programu Matlab in simulacijskem okolju Simulink. Namen diplomskega dela je prikaz delovanja stikalnega pretvornika navzdol, simuliranje z uporabo prej omenjenih programov, razumevanje delovanja PID regulatorja ter njegovo umerjanje. Delo je razdeljeno na tri večje teoretične dele, ki sestojijo iz teorije delovanja stikalnega pretvornika navzdol in izračuna potrebnih elementov, ki bi pomagali pri realizaciji takšnega vezja. V drugem delu je predstavljena teorija o delovanju in umerjanju posameznega člena PID regulatorja po Ziegler-Nicholsovi metodi. V tretjem delu pa je predstavljen analogen model regulatorja in njegova sestava ter teorija diskretno časovnega regulatorja in dve težavi ter njuni rešitvi. Predstavljene so funkcije, ki so bile uporabljene v kodi za potrebe simulacije grafov, izvažanja podatkov in obdelave. Zbrane so tudi ideje o nadaljevanju raziskave in izboljšave simulacij.

• Title: Simulation of a switching voltage converter with a regulator

Abstract

The thesis is about the voltage regulation of a switching voltage converter using a PID controller. All simulations were conducted in the Matlab program and the Simulink simulation environment. The purpose of this thesis is to demonstrate the operation of the switching voltage converter, simulate it using the mentioned programs, understand the operation of the PID controller, and calibrate it. The thesis is divided into three main theoretical parts, firstly explaining the theory of the switching voltage converter's operation and the calculation of needed elements, which would help with the realization of a circuit. The second part presents the theory of the operation and calibration of individual components of the PID controller using the Ziegler-Nichols method. The third part introduces the analog model of the controller and its composition, as well as the theory of the discrete-time controller and two problems along with their solutions. Functions used in the code for simulating graphs, exporting data, and processing are also presented in the thesis. It also disscusses the ideas for further research and improvements to the simulations.
