Abstract :
We develop an adaptive harmonic steady state control for disturbance rejection. HSS control extends higher harmonic control and convergent control developed for helicopter vibration reduction and rotor imbalance control. HSS control is applicable to stable systems with tonal or multi-tonal disturbances. The adaptive HSS algorithm is easy to implement and robust in the sense that no modeling information is required aside from the number of disturbance harmonics.
