Sliding mode control of a doubly-fed induction generator

Abstract

This paper deals with the sliding mode control of a doubly-fed induction generator. The controller synthesis, based on a dynamical equivalent circuit representation of the machine, is presented. Then, its robustness against parametric variations of the system is evaluated and compared to the results obtained with a linear control scheme. The controller is finally validated by experimental results.

FPGA Design for Direct Sliding Mode Current Control of a Synchronous Machine

“…Equations (13) and (14) show that, neglecting the terms of voltage drops, the sign of the switching function time derivatives depends essentially on -The applied voltage vector in the synchronous refrence frame.…”

“…The sliding mode control method was firstly proposed by [11], [12] and was widely applied for the control of electrical drives [13], [14], [15]. This type of control is dedicated to the control of variable structure systems (VSS), which are based on discontinuities in the state space.…”

Design of a switching table for direct power control of a DFIG using sliding mode theory

“…Some works have been conducted to use the sliding mode theory in order to synthesize the switching table exhaustively [10]. In fact, thanks to its robustness to the parameters variations and external disturbances, the sliding mode method is used with success for the control of electrical drives in particular of synchronous machine [11], [12] and [13], asynchronous machine [14], Induction machine [15] and [16], doubly feed induction generator [17], [18] and [19]. This work aimed to present a synthesis of direct controls for electrical systems using the sliding mode theory.…”
