✦ Synopsis

This work combines two well-known approaches to control: dual control and harmonic control. The combination results in high speed of adaptation and the possibility of using feedback controllers in practical situations where traditionally feedforward controllers were preferred. The use of frequency-selective "lters results in fast adaptation without substantial increase in on-line computing e!ort. The approach proposed is more suitable for adaptive cancellation of periodic output disturbances. Dual controllers are computed around each relevant frequency of the disturbance and the control input to the plant is synthesized from them. Simulations illustrate how the control scheme works.
