Remaining Useful Life Control of a Deteriorating Wind Turbine with Flexible-Shaft Drive-Train

ABSTRACT
In this paper, we propose a degradation-aware control approach that allows to control the remaining useful life of a deteriorating wind turbine system. We consider more particularly the degradation caused by the dissipated energy in the drive-train, and we aim at controlling it by acting on the control gain of the generator torque imposed at the output of the drive-train. We propose an observation and control structure for this degradation control problem. By applying control techniques, such as optimal control and state-feedback control, we control the degradation process while guaranteeing the stability of the wind turbine system. A numerical case study illustrates the advantages of controlling the degradation using the proposed approach for a system suffering from load effects with the aim to correct its remaining useful life.
