Cascade sliding mode controller for self-excited induction generator

Abstract

This paper presents a simple control structure based on the sliding mode algorithm for an isolated-loaded induction generator (IG). The machine delivers an active power to a dc-load via a converter connected to a single capacitor on the dc side. Since the converter/capacitor model is nonlinear, the sliding mode technique constitutes a powerful tool to ensure the dc-bus voltage regulation. The computer simulations are provided to verify the validity of the proposed control algorithm.
