Oil well drilling has always been one of the challenging subjects in engineering, and during the past decade in order to enhance the efficiency, this process has been developed in many aspects which cause more difficult problems in... more
A mathematical model describing the dynamic characteristics of the vehicle needs to be solved for predicting the future position and orientation of vehicle relative to the changing environment. By reducing the time consumed to solve the... more
ABSTRACT This paper presents a short comparison of different existing and proposed wave prediction models, which in turn are used to control wave energy converters (WEC) in irregular waves. The objective of the control action is to... more
This work addresses the construction of a four- wheel, nonlinear vehicle dynamic bond graph model and its implementation in the 20sim modeling and simulation environment. Nonlinear effects arising from the coupling of vertical,... more
The premise of this thesis is to compare valve control and pump control methodologies for excavator boom lift applications. Equations of motion were derived from classical bond graph techniques and simulations were run via AMESIM modeling... more
This paper examines methods that can be adopted in early stage or retro t design of actuator subsystems, and is motivated by the modern trend toward retro tting legacy hydraulic actuation of submarine control surfaces with... more
The context of this PhD thesis is the modelling and design of mechatronic systems. The study is positioned in the early design stage of the conception cycle (V-Cycle), where the main efforts have to be produced in terms of methodology, to... more
Los sistemas dinámicos pueden ser analizados de diferentes maneras, sin embargo no todos los métodos permiten su aplicación computacional. El presente trabajo describe cómo resolver sistemas dinámicos aplicando el método bond graph,... more
Offshore hydraulic cranes are difficult to operate safely, accurately and efficiently due to their heavy structure, large inertia, non-intuitive control interface and load sway issues that result from external disturbances. This paper... more
Magnetic Levitation has been a keen area of research, especially in the field of automotive where low losses due to friction and low energy consumption are important considerations. This paper offers... more
This paper presents a new way to derive an optimal control system for a specific optimisation problem, based on bond graph formalism. The procedure proposed concerns the optimal control of linear time invariant MIMO systems and can deal... more
This paper presents a Bond Graph (BG) modelling approach to add and exploit on existing Modelica models some information on the energy structure of the systems. The developed models in the ThermosysPro library (Modelica-based) are already... more
For the benefit of engineers working outside the bicycle industry, this paper describes some engineering considerations related to the development of a new model full suspension bicycle fork. The impact of market forces on the development... more
Abstract. This work deals with the development of a feedback controller for an active suspension system to be applied in a high performance elevator. The elevator has a double-deck cabin and will be used in a 200 [m] course guide in a... more
Physical systems are by nature continuous. Perceived discontinuities in system models are in reality nonlinear behaviors that are linearized to reduce computational complexity and prevent stiffness in system analysis and behavior... more
This paper presents modelling and simulation of multi-scroll chaotic attractors by using a new simple and more general bond graph model. For this purpose, the multi-segment non-linear resistor in Chua’s circuit is modelled by using... more
