Development of a PC-based Real Time Power Electronics Control Platform: Entwicklung einer Echtzeitregelungs- und Steuerungsplattform mit industriellen ... für leistungselektronische Anwendungen - Brossura
Inhaltsangabe:Abstract: In this thesis it was shown that it is possible to set-up a very fast and flexible realtime controller using only off-the-shelf components on a PC platform. To best fit the requirements, the used hardware and software has been chosen carefully and compared with other market products. After evaluating the timing and handling structure, the real-time controller and the system drivers were implemented using the 'C' program language. To ensure flexibility, this program has been tested on two different hardware configurations. Timing analyses and measurements are compare for the two configurations. All code is written to be easy to understand and quickly learned by students. To prove the system capabilities, a PI control algorithm has been implemented to control the torque of a DC machine. The system ran on a 333 MHz PII with algorithm times of about 600ns and an overall sampling rate of 20kHz. This very flexible system, together with the real time operating system of RTLinux and Linux, makes it possible to build a control platform for power electronics which can be easily adapted to fit almost every requirement in a very short time. The superior computation power of standard PCs (and the possibility to upgrade the CPU) is a decisive advantage to common DSP solutions - especially when system cost is an important factor. The use of open source operating systems enables full control and survey of the whole system. Software and utilities for almost all applications is available in source code. Competent help can be obtained from an active community via the internet as well as from professional companies. Together, these facts ensure that the lifetime of this PC based control platform is not restricted by the availability of spare parts from single companies. And it is not limited by the software and hardware possibilities of the year 2001. Inhaltsverzeichnis:Table of Contents: 1.Introduction1 1.1Organization2 1.2Conventions2 2.Requireme
