Abstract
A system for extracting a signal component from an output signal of a dynamic system. The system comprises a state observer and a corrector filter. The state observer is adapted to track a signal component that represents dominant dynamics in the output signal of the dynamic system and provide an estimation signal representing an estimated signal component in the output signal of the dynamic system. The corrector filter is adapted to compensate for a mismatch between the estimation signal and the actual signal component that represents the dominant dynamics in the output signal. A combination of the estimation signal with an output signal of the corrector filter can provide a synthesized signal including the signal component that represents the dominant dynamics in the output signal.
