Řídicí algoritmy pohonů elektromobilů

Abstract

This bachelor’s work is concerned with problems relating to actual electric vehicles. The work contains recherche of concepts of electric vehicles that is aimed to the principal parts. Among these parts is comprised an electromotor, a voltage source inverter, a power source and a control section. Furthermore the work describes the claims on these parts. The most important claim is the pretension to economization. It is educed from a current situation of society, when the main theme in automobile industry is an endeavor after saving money or more precisely a fuel. The electromotor become more economical in using an appropriate control algorithm. The two best known algorithms are the vector oriented control and the direct torque control which there are also analyzed here. The characteristics of regulating structure are advantageous to check before the initiation into production. This attestation is possible to do by using simulation software. The simulation results of the vector oriented control are introduced at the ending of this work.
