【 摘 要 】

More-Electric Aircraft (MEA) underlines the utilization of the electrical power to power the nonpropulsive aircraft systems. The aircraft electric actuator (AEA) is an emerging aerospace technology that aims at replacing hydraulic systems with self-contained actuators operated solely by electrical power. This is one of the most important techniques of electric loads of the future more electric aircraft. However, the MEA put some challenge on the aircraft electrical system either in the amount of the required power or the processing and management of this power. In this paper, a novel fuzzy rule based dc-bus voltage switched control method of three-phase voltage source pulse widthmodulated rectifiers (VSRs), implemented to solve the problem of flexible voltage regulating under dynamic loads, is proposed under a nonlinear control in rotating synchronous coordinates d−q. Several linear controllers are designed on different operating points of the VSR, and fuzzy controller is implemented on the VSR system according to certain switching law. The stability of the proposed control approach is guaranteed based on the fuzzy based controller. Simulation and experimental results show that the desired control performance is obtained in the voltage regulating of a VSR with wide-range rapidly varying load. Compared with the classical PI controller fuzzy controller is proved to have less effective under a wide range rapidly varying active load.
