Multi-User Massive MIMO Channel Estimation Based on Kalman Filters

Creator:

Yao, Zhaoda

Abstract:

In wireless communication, channel state information (CSI) is essential for data detection. Fast fading coefficients estimation is important in order to acquire accurate CSI. Kalman filters (KF) are widely used for real time parameter estimation and can be used to estimate the fast fading coefficients of a mobile communication channel....

Grid Voltage Frequency Estimation Using an Adaptive Complex Master-Slave Unscented Kalman Filter

Creator:

Muñoz Constantine, Juan Pablo

Abstract:

Due to the popularity of electronically controlled loads and the widespread use of alternative energy sources such as wind turbines and solar cells, the power quality at the distribution level must be carefully monitored. One of the many different means to monitor power quality is through frequency measurements. Nonlinearities cause...

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...

Masters Thesis
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...

Masters Thesis
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...

Masters Thesis
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...

Masters Thesis
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...

Masters Thesis
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...

Masters Thesis
Fuzzy logic control of an inverted pendulum with vision feedback

Creator:

Holzapfel, Frank G.

Abstract:

Recent technical progress has made new forms of controller implementations on computers possible. Especially the technique of Fuzzy Logic Control has found a growing number of applications. Also the development of fast A/D converters has made the acquisation of data with vision based systems possible. In this project we combine...
