A new frequency domain system identification method

A new frequency domain system identification method

A new frequency domain system identification method based on a multi-frequency input signal is proposed. Frequency contents of the oscillating signal are estimated using a modified Kaczmarz algorithm proposed in this paper. Lyapunov stability analysis is performed for this new Kaczmarz algorithm and transient bounds for estimation error are established. Moreover, a new method for estimation of ...

Frequency Domain System Identification

Robust New Method in Frequency Domain Watermarking

This article presents a new and robust watermarking method in the frequency domain that improves over the existing ones. It is robust to JPEG compression, very configurable, simple, efficient and very easy to implement. Apart from JPEG test, it shows very good results in all tests applied.

Frequency domain versus time domain methods in system identification

For some reason I now forget, Keith Glover and I were asked to prepare a discussion paper on frequency and time domain methods in system identi cation by the organizers of the IFAC symposium on System Identi cation in Darmstadt 1979. I visited Keith in Cambridge in April 1979 to prepare our paper. It later evolved into an Automatica arcticle. Since then, there has been a useful development of s...

Frequency domain subspace identification of a tape servo system

As capacity demands for magnetic tape storage systems grow, servo actuator design for tracking data on high density tape media presents new modeling and control design challenges. In this paper a frequency weighted subspace identification algorithm is presented for control relevant model estimation of a tape servo actuator. Common to other subspace identification methods, the proposed algorithm...
