Efficient analysis of oscillators with multiple time dimensions
(2005)
Harmonic Balance (H B ) analysis is an established technique for the analysis of nonlinear
circuits. In this thesis, we present a method to find the transient and steady-state behavior of
oscillators based on a harmonic ...
Vision-based trajectory tracking algorithm with obstacle avoidance for a wheeled mobile robot
(2005)
Wheeled mobile robots are becoming increasingly important in industry as means of
transportation, inspection, and operation because of their efficiency and flexibility.
The design of efficient algorithms for autonomous ...
Adaptive control of a parallel robot via backstepping technique
(2006)
Parallel robots have attracted more and more attention in recent years due to their
kinematical and mechanical advantages. However the complicated high nonlinear model
with unknown parameters and singularities make the ...
Dynamic model and control of vehicles
(2006)
In this thesis the author develops a 14 degrees-of-freedom (DOF) full-car model. The
model draws from and improves upon features and setups of certain existing vehicle
dynamics models. The proposed model provides a means ...
Nonlinear controller design for a buck converter
(2006)
This thesis presents five different nonlinear control techniques for voltage regulation of a
DC-DC buck converter operating in continuous conduction mode. A state space
averaging model is derived from a non-ideal buck ...
Observer-based chaos synchronization for secure communications
(2006)
Chaos, with reference to chaos theory, refers to an apparent lack of order in a system
that, nevertheless, obeys particular laws or rules. The chaotic signals generated by
chaotic systems have some properties such as ...
Attitude estimation and control of a ducted fan VTOL UAV
(2007)
A significant area of current research is to develop aircraft which are unmanned. More specifically, some researchers are focusing on hovering type aircraft, or vertical take-off and landing (VTOL) aircraft. Since these ...
Nonlinear dynamics of railway wheelsets incorporating randomness
(2007)
The thesis is to investigate the dynamic behavior of a single-axle railway wheelset and identify its chaotic behavior by means of time history, phase portrait, Lyapunov exponents, information dimension, bifurcation diagram ...
Integrated mechanisms for QoS and restoration in mesh transport networks
(2007)
Survivable networks have the capability to survive from the events of network components failures. The resilience mechanisms in these networks protect and restore the impaired communication paths by using spare capacity. ...
Non-collocated control of vibration of a three-DOF structure using the electromagnetic vibration absorber
(2007)
Vibration control is very important in many areas including machine operation and
daily life. Semi-active vibration control integrates a tuning control scheme with a tunable
vibration absorber for suppression of vibration ...
