This study focused on fuel cell electric unmanned aerial vehicle (FC-EUAV) in order to find solutions to problems such as the short-lived and limited long flight endurance of unmanned aerial vehicles operating with fossil ...

Gain-phase margins-based delay-dependent stability analysis of pitch control system of large wind turbines

Türksoy, Ömer; Ayasun, Saffet; Hameş, Yakup; Sönmez, Şahin (Sage Publications Ltd, 2019)

This paper investigates the effect of gain and phase margins (GPMs) on the delay-dependent stability analysis of the pitch control system (PCS) of large wind turbines (LWTs) with time delays. A frequency-domain based exact ...
