In this work piezo-stack actuators mounted in consoles are utilized to actively dampen vibrations of a flexible car body structure by introducing bending moments. Using an example of a heavy metro vehicle the complete design for the active vibration damping system is presented. Both analytical modeling and a system identification of the vehicle are described, issues of modal representation and ...

Neural networks are applicable in identification systems from input-output data. In this report, we analyze theHammerstein-Wiener models and identify them. TheHammerstein-Wiener systems are the simplest type of block orientednonlinear systems where the linear dynamic block issandwiched in between two static nonlinear blocks, whichappear in many engineering applications; the aim of nonlinearsyst...

A new theory for the rational covariance extension problem (with degree constraint), or simply the RCEP, has recently emerged with applications in high-resolution spectral estimation, speech synthesis and possibly new applications in time series analysis and system identification. This paper establishes some new theoretical results on the RCEP via an alternative analysis. In one result we show ...

For a little over seven years, my husband and I have lived in Downtown Huntington Beach, our house being a pastel yellow with white trim 1922 cottage-style house—complete with white picket fence. While there are still numerous other " historical " homes in our area, in many cases dating from the years marking the construction of the Southern Pacific Railroad, many more have given way to new tow...
