This paper presents performance comparisons of two graphical techniques for modeling and simulation of complex nonlinear mechatronic systems. These techniques are respectively Bond Graph (BG) structural approach and Block Diagram (BD) which is a functional approach. They are applied for the modeling of single wheel electrical vehicle. The BG model is elaborated under 20-SIM environment, while the...
This paper presents the dynamic modeling of a linear switched reluctance motor. This modeling is based on the exploitation of the magneto-static finite elements model built for the studied motor. The static characteristics of flux and forces, determined by the two dimensional finite element simulations are grouped into response surfaces. These surfaces are used, under low operating speed conditions,...
This paper presents a comparative study and analysis between various models of Photo-Voltaic (PV) used on solar vehicles, which have been formulated exclusively using the data sheet parameters.

Operating is the aim of this paper, the control of a hybrid vehicle movement in the electric mode. A 2DOF PID controller is designed for the velocity, position, and acceleration control of the vehicle. A dynamic model of the electric vehicle is achieved. The simulation results are compared to those obtained from the use of classical PID control approach.
The smart grid is a system composed of different subsystems and different objects, hardware and software. In this paper, the smart grid is presented.

In fact, a systemic modeling based on the Objectives Oriented Project Planning (OOPP) method is presented to model the smart grid...
This paper presents an analysis and modeling of a micro-smart grid using the systems modeling language SysML. Worldwide, a large number of environmental problems are associated with the energy production. However, global warming, greenhouse gases, Co2 emissions and climate change are the most significant impacts of energy generation damage. Solving these environmental issues, in the context of optimizing...
This article deals with the design and modeling of PID regulators with two degrees of freedom for the thermal phase of the hybrid vehicle. It shows how to regulate the speed of a vehicle using a PID control with two degrees of freedom with a set point weighting. Two main objectives of this controller are tracking set points and rejecting load disturbances at the same time. A number of control algorithms...

This paper presents the design of Permanent Magnet Synchronous Actuator. The Permanent Magnet Synchronous Actuator is designed for piloting SBW direction. The output of the designed actuator is then coupled with a rotary-to-linear motion transformation organ and applied as a force to the wheel axis to obtain imposed direction and speed. The torque obtained from the finite element simulation under...
The performance and the cost of photovoltaic systems (PV) can be improved by employing high-efficiency power control with maximum power point tracking (MPPT). Many maximum power point trackers algorithms have been developed to maximize the produced energy and a lot of these are well established in the literature. In this paper, a comparative study of the most used MPPT algorithms is achieved. Using...
The effective radius of the tire as well as the rolling resistance of a vehicle are two important variables that affect its dynamics, performance and comfort. Because of their dependence on tire pressure, the assessment of these variables can be used to monitor tire pressures using an indirect approach. By considering the vertical, longitudinal and rotational dynamics and using the wheels' angular...
