摘要：

This paper presents a vector control system of the self-excited induction generator (SEIG) employing an indirect rotorfield- oriented (IRFO) control algorithm. In the system, the excitation is achieved by means of a current-controlled voltage source inverter and a single electrolytic capacitor. The objective is to keep the DC voltage across the capacitor constant and equal to the reference value, regardless of changes in the rotor speed and load. To achieve this, two different-type fuzzy logic (FL) voltage controllers are proposed and investigated. The performance of the developed FL voltage controllers is evaluated by comparison with the optimal-tuned classical PI controller. The analysis is carried out for wide ranges of rotor speed, load and DC voltage, both on the simulation and experimental level.
