Gain-phase margins-based delay-dependent stability analysis of pitch control system of large wind turbines
(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 ...
Analysis of combined passively and actively morphing blade root chord length and blade taper for helicopter control
(Emerald Group Publishing Ltd, 2019)
Purpose The purpose of this study is to examine the effect of passive and active morphing of blade root chord length and blade taper on the control effort of the flight control system (FCS) of a helicopter. Design/method ...
