Abstract:The next generation rotor, active control rotor are being researched and developed for vibration, noise reduction and performance improvement.However, actuator output constraints lead to significant loss of optimal performance in classic higher harmonic control (HHC) algorithms.This paper proposed an iterative-QP method based on 1-norm constraints that can achieve performance improvements. Details of the iterative-QP method in vibration reduction application were discussed.Comparison with scaling, truncation, auto-weighting, SQP and the QP method based on 1-norm constraints, the benefits of the iterative-QP method when dealing with actuator constraints were shown for a linear representation of a four-blade rotor model augmented with active trailing edger flap.
