VIBRATION CONTROL OF THE TURBINE BLADE USING QUANTITATIVE FEEDBACK THEORY

摘要：

Quantitative Feedback Theory (QFT) introduces the new technique to design one-point feedback controllers for distributed parameter systems (DPS).In this regard, this paper tried to decrease the amplitude based on the controlled torques which have been applied at the joint of hub.Considering that the governing dynamic equations on the blade are nonlinear, using QFT can reach the desired results.This approach has the ability of solving uncertain and nonlinear problems, therefore it is tried to control the blade vibration appropriately.In the applied method in this paper, the aim is: exerting the torque on the base of the blade against the applied forces then designing the controller using Quantitative feedback Theory.QFT is one of the robust control methods which used in frequency domain to solve uncertain problems.
