Intelligent systems for active vibration control in flexible engineering structures / by Ji Xiaoxu.
(2008)
Vibration arises in almost all moving structures. Vibration control is important to many applications such as robotic arms, aircraft wings, buildings in wind, vehicle transmission systems,to name but a few. The objective ...
Robust control of DC-DC boost converter / by Hisham Mahmood.
(2008)
In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller ...
End-to-end shared restoration in multi-domain networks / by Zhiying Gao.
(2008)
Emerging multi-service data applications require high-bandwidth high-quality connectivity across multiple network domains, each of which is generally controlled by an independent service provider. These applications ...
Design and modeling of a CMOS VCO using wave digital filters / by WeiBo Li.
(2007)
Wave digital filters (WDFs) transform an analog network into a topologically equivalent digital structure. A natural application of WDF is the simulation of electric circuits since measurements of any desired node voltages ...
Asymptotic performance of M-ary signals on Rician fading diversity channels / by Hongwei Zhang.
(2007)
In this thesis, we will study the average symbol error rate of M-ary signals on wireless Rician fading channels at high average signal-to-noise ratio (SNR) in both single-carrier and multicarrier orthogonal frequency ...
Frequency domain tuning approach for adaptive feedforward controllers
(2003)
Feedforward control provides a means for compensating measurable disturbances before the
process output is affected. A novel tuning strategy for tuning feedforward controllers in
frequency domain is developed in this ...
Attitude stabilization of a quadrotor aircraft
(2004)
The quadrotor aircraft has seen a growing interest in the research community over
the past few years, with a focus on modeling and control however. Early rotating
wing aircraft pioneers designed similar four-rotor aircraft ...
Congestion and admission control in WDM optical networks
(2006)
The demand for more communication bandwidth and network resources, has pushed
researchers to find faster and more reliable data communication networks. Wavelength
division multiplexing (WDM) is a promising technology to ...
A Tunable high-static-low-dynamic-stiffness isolator and a fuzzy-neural network based active control isolator
(2009)
Excessive vibration can be detrimental to a wide variety of structures and machines. Vibration isolation is an effective means to suppress vibration. This study focuses on development of some new techniques to improve ...
Study of two different tunable vibration absorbers : variable stiffness absorber and variable damping absorber
(2003)
A structure or machine w ill vibrate at the frequency of excitation when excited by a
harmonic force. Vibration of the structure can be suppressed using a vibration absorber by
setting the absorber’s natural frequency ...
