Abstract

A robust control methodology for the dynamic response control of a rotating blade at a constant speed is presented. The blade, modeled as a tapered thin-walled beam with fiberreinforced composite material, is exposed to external load. The dynamic response characteristics of a rotating composite beam are investigated in terms of various beam design elements such as ply angle, taper ratio, etc. In order to extend their fatigue life and improve the efficiency of the rotating blades, integrated tailoring system, consisting of active robust control with estimator and passive structural tailoring scheme, are implemented. To this end, considering modeling uncertainties and external disturbance condition, a sliding mode control is proposed and its performance and robustness are compared with the conventional Linear Quadratic Gaussian Control. Discussions and conclusions are outlined.
