This paper develops consistent model and moment selection criteria for GMM estimation. The criteria select the correct model speci"cation and all correct moment conditions asymptotically. The selection criteria resemble the widely used likelihoodbased selection criteria BIC, HQIC, and AIC. (The latter is not consistent.) The GMM selection criteria are based(More)

In this paper, we present a new energy-based saturated control law for underactuated cranes with double pendulum payload dynamics. Specifically, we construct a new energy storage function to enhance the internal state coupling and then design a saturated output feedback controller. After that, rigorous theoretical analysis is provided to prove that the(More)
A signal su ers from nonlinear, linear, and additive distortion when transmitted through a channel. Linear equalizers are commonly used in receivers to compensate for linear channel distortion. As an alternative, nonlinear equalizers have the potential to compensate for all three sources of channel distortion. Previous authors have shown that nonlinear(More)
Acknowledgments I am deeply thankful to my supervisor Professor Al Bovik. Al has been enthusiastically inspiring and encouraging me since I joined his group. Without his excellent guidance and tremendous support, this research w ork would have been impossible. My heartfelt gratitude also goes to my co-supervisor Professor Brian Evans for his great(More)
We study the problem of estimating signal parameters from a noisy data sequence containing superimposed damped sinusoids. We propose three novel methods by combining the reduced-rank Hankel approximation and the Matrix Pencil method. We demonstrate that two of the proposed methods signi cantly outperform both the original Matrix Pencil method and the modi(More)
As a powerful large scale construction tool, a tower crane is a strongly nonlinear underactuated system presenting complicated dynamical characteristics. Existing control methods for tower cranes are developed on the basis of simplified (i.e., linearized/approximated) crane dynamics, and most of them require exact model knowledge. However, practical tower(More)
