摘要: Damping of the primary bending mode a tower (12) mounting wind turbine having control (36) for providing pitch blade angle reference signal (40) to modulate blades (1) through change mechanism (38) constant power is provided by generating as integral (104) summation (266) torque/power controlling rate (98) with an estimated acceleration (255) generated filtering (250, 252, 254) following transfer function ##EQU1##
