Implementation of DSP Based on Vector Control Model of AC Excitation Control System for a New Hybrid Excitation Synchronous Generator

Abstract

Permanent magnet generator has the advantages of simple structure, reliable operation and low loss, but it is not easy to adjust voltage, which restricts its wide application. This paper presents a new type of hybrid excitation synchronous generator (HESG) and establishes the mathematical model and simulation of vector control based on its AC excitation system to control the output voltage as the expectation. In application, DSP, as the control system, is traditionally programmed and debugged off-line, which requires heavy workload. Whereas, the design based on model greatly shortens the development cycle. By connecting MATLAB simulation environment to the CCS development environment, the simulation model can be translated into code and downloaded to the targeted DSP through an emulator. This implementation will have specific and indispensable significance for the hardware development and software debugging of motor control system.
