Control of Wind Conversion System Used in Autonomous System

Abstract

The topology based on permanent magnet generator (PMSG) and diode bridge rectifier is frequently used in small wind energy conversion system since it is robust and easy to control. This paper presents a robust control for the wind conversion system based on PMSG and boost DC/DC converter in the aim to maintain the generator rectified voltage at a reference voltage corresponding to the reference power imposed by the supervisory module. The reference power control is guaranteed without measuring the wind speed. The sufficient conditions for state feedback stabilizing designed controller are given in terms of solutions to a linear matrix inequality (LMI) and H . Simulation tests results are carried out for this wind conversion system topology which operates in a multi-source system, in order to visualize the feasibility of the proposed method.

Intelligent power control of wind conversion system based on Takagi–Sugeno fuzzy model

“…The T-S approach has been investigated in the control of the WCS as in previous works. 24,25 These papers have highlighted the advantage of the LMI, which still needs the operational states of the WCS at MPP.…”

“…A robust control for the wind conversion system based on PMSG and DC / DC boost converter with the aim of maintaining the voltage of the rectified generator at a reference voltage corresponding to the reference power set by the supervisor module. Reference power control is guaranteed without measuring wind speed [22]. Modeling of a three-phase induction generator driven by a horizontal axis wind turbine is described.…”
