Modeling and analysis of limit cycles in buck converters under PI control
(2005)
A zero order hold equivalent discrete-time model of the buck converter for computing its
large signal frequency-response is developed and experimentally verified. It is shown that
with a dc bias and a sinusoidal variation ...
Investigation into the use of ELG for stand alone power system frequency control
(2006)
The use of ELG for stand alone power system frequency control is investigated in this
thesis. Characteristics of a stand alone power system with PCR-ELG are presented.
Dynamic simulation of the system is developed using ...
Radio resource allocation in OFDMA system
(2006)
In this thesis, orthogonal frequency division multiple access (OFDMA) system is considered.
Assuming perfect knowledge of instantaneous channel conditions for all users, we propose resource
allocation algorithms to ...
Adaptive backstepping based nonlinear control of an interior permanent magnet synchronous motor drive
(2005)
Permanent magnet synchronous machines (PMSM) have shown increasing
popularity in recent years for industrial drive applications due to the recent developments
in magnetic materials, power converters, and digital signal ...
Time-domain steady-state analysis of circuits with multiple adaptive grids
(2005)
An effective adaptive algorithm to calculate the steady-state response of circuits is developed.
This algorithm offers a powerful alternative to traditional steady-state simulation techniques,
such as the shooting method ...
Modeling of PWM boost converters for continuous and discontinuous inductor current modes
(2006)
Owing to the relatively more complicated nature of the boost converter with non-ideal
elements and operating in continuous and discontinuous inductor current modes, a
parsimonious large signal and small signal model for ...
Design and control of a 6 DOF biped robot
(2006)
This thesis is composed of the following five parts: construction of a 6 Degrees of
Freedom (DOF) biped robot, control system design, analysis of forward
kinematics and inverse kinematics, walking pattern planning, and ...
Robust control of multi-stage web systems
(2007)
Web handling systems are widely used in industries such as pulp and paper, printing press, and steel milling. Tension variations in web materials are very common in operation and tension control is critical to the quality ...
Design, analysis and passive balance control of a 7-DOF biped robot
(2007)
Biped robots have many advantages than traditional wheeled or tracked robots. They have better mobility in rough terrain and can travel on discontinuous path. The legs can also provide an active suspension that decouples ...
Pulsatile flow interaction with a stented artery : compliance mismatch effects
(2007)
Atherosclerosis is a group of diseases characterized by thickening of the arterial wall resulting in a reduction in the cross-sectional area of the lumen. One of treatments for these artery diseases is stent angioplasty. ...
