Improved Lyapunov-based decentralized adaptive controller

Creator:: Dai, Reza A.
Abstract:: An improved robot manipulator decentralized non-linear adaptive controller that performs well in the presence of disturbances with unknown parameters and non-linearities is presented in this work. The proposed decentralized adaptive structure is a modification of the controller developed by Seraji [13-17] and is characterized by an auxiliary signal that compensates...

Proposed implementation of a near-far resistant multiuser detector without matrix inversion using Delta-Sigma modulation

Creator:: Myers, Timothy F.
Abstract:: A new algorithm is proposed which provides a sub-optimum near-far resistant pattern for correlation with a known signal in a spread-spectrum multiple access environment with additive white gaussian noise (AWGN). Only the patterns and respective delays of the K-1 interfering users are required. The technique does not require the inversion...

Robust nonlinear decentralized control of robot manipulators

Creator:: Jimenez, Ronald, 1964-
Abstract:: A new decentralized nonlinear controller for Robot Manipulators is presented in this thesis. Based on concepts of Lyapunov stability theory and some control ideas proposed in [3]-[7], we obtain continuous nonlinear decentralized control laws which guarantee position and velocity tracking to within an arbitrarily small error. Assumptions based on physical...

Modified limiting dilution analysis : a mathematical model with biological interpretation

Creator:: Maier, Stefan H.
Abstract:: A mathematical model of Limiting Dilution Analysis for two limiting parameters is presented and investigated. Limiting Dilution Analysis is a microbiological cell assay developed for immunological application. In the given case we deal with the interaction between B lymphocytes, macrophage derived factor and T-independent antigens. The state of the art...

Active robust control of cable-stayed bridges

Creator:: Scheer, Dietmar
Abstract:: Long bridges tend to develop large deformations under the action of intense dynamical loads such as wind or earthquakes. Unless these deformations are controlled in some fashion, the structure might suffer damage or even collapse. One possible solution to this problem is to apply external forces to the bridge through...

A fast trajectory tracking adaptive controller for robot manipulators

Creator:: Tagami, Shinsuke
Abstract:: An adaptive decentralized nonlinear controller for a robot manipulator is presented in this thesis. Based on the adaptive control schemes designed by Seraji [18], Dai [30], and Jimenez [31], we redesigned and further simplified the control algorithm and, as a consequence, we achieved better path tracking performance. The proposed adaptive...

Wavelet analysis as a signal processing method for multiresolution signal decomposition in natural resources applications

Creator:: Tu, De Yun
Abstract:: The purpose of this thesis is to apply the wavelet transform WT to multiresolution structures for analyzing the information content of images based on multiresolution signal decomposition of the wavelet representation. The advantage of the wavelet transform is the fact that it uses different building blocks than the Fourier's sines...

Joint convolutional and orthogonal decoding of interleaved-data frames for IS-95 CDMA communications

Creator:: Rabinowitz, David
Abstract:: IS-95, an interim standard proposed for future digital personal communications systems, uses two levels of encoding of digital data for error control and compatibility with code-division multiple access (CDMA) transmission. The data is first convolutionally encoded and the resulting symbols are interleaved and then groups are encoded as orthogonal Walsh...

A high-performance, low power and memory-efficient VLD for MPEG applications

Creator:: Zhang, Haowei
Abstract:: An extremely important area that has enabled or will enable many of the digital video services and applications such as VideoCD, DVD, DVC, HDTV, video conferencing, and DSS is digital video compression. The great success of digital video compression is mainly because of two factors. The state of the art...

Non-data aided parametric based carrier frequency estimators for bursty GMSK communication systems

Creator:: Kandukuri, Ajay
Abstract:: Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...
