Output Control Approach for Delayed Linear Systems with Adaptive Rejection of Multiharmonic Disturbance
Publisher: 19th World Congress The International Federation of Automatic Control
We present a new output control approach for a linear plant with input delay and an unknown multiharmonic disturbance acting on the input and the output. To solve this problem, we combine the well-known predictor feedback approach with the state observer and adaptive scheme that identifies the frequency of the disturbance. Compared to the existing approaches, the structure of our adaptive scheme is the simplest and the results apply to plants that are unstable, non-minimum phase, and have an arbitrary relative degree.
