Abstract

Blade Pitch Controller (BPC) that can cope system uncertainties is one of the most interesting topics in wind energy engineering. Therefore, this paper presents a step towards the design of robust non-fragile BPC for wind energy conversion system. The proposed approach presents all boundaries of stability region that can guarantee robust stability (RS) over a wide range of operating conditions. The proposed technique results from the complementarity of both Root-Locus and Routh-Hurwitz (RL/RH) approach. Continuous variation in the operating conditions is tackled through a new hybrid control technique based on the referential integrity of both RL/RH and Kharitonov (Kh) theorem. Simulation results confirm the effectiveness of the proposed designing approach in computing the most resilient and robust controller.
