A passivity-based controller, which takes into account saturation of the magnetic material in the main flux path of the induction motor, is developed to provide close tracking of time-varying speed and flux trajectories in the high magnetic saturation regions. The proposed passivity-based controller is experimentally verified. Also, a comparison between the… (More)
Applications of the Virtual Test Bed (VTB) to a power electronic circuit and an electric drive system are described. The VTB is a software environment that has been developed for design, analysis, and virtual prototyping of large-scale multi-technical systems. It has the capability of integrating models, which have been created in a variety of languages… (More)
The Virtual Test Bed (VTB) is a software environment that supports design, analysis, and virtual prototyping of electric power systems, with an emphasis on naval applications. This paper describes the status of development of the VTB and its use in the multi-technical field of ship power systems.
Hybrid Electric Vehicles (HEVs) are the subject of many designs and simulations. The uniqueness of the proposed hybrid electric vehicle is its combination of an energy source (fuel cell system) with two storage devices (a battery bank and a super capacitor). This research focuses on optimization of the electrical system by use of a simulation model. As a… (More)
A virtual prototype of a hybrid electric vehicle (HEV) is created within the Virtual Test Bed (VTB) environment, which has been developed for modeling, simulation, analysis and virtual prototyping of large-scale multi-technical dynamic systems. Attention is focused on the electric system, which is composed of (i) a fuel cell system as a prime power source,… (More)
This paper introduces a new software environment, the Virtual Test Bed (VTB), which has been particularly developed for graphical and visual simulation of large-scale electric power systems. A possible application of the VTB to analysis of an electric drive system is also described.
A new modeling and simulation tool, the Virtual Test Bed (VTB), is introduced. The VTB is a software environment that has been developed for design, analysis, and virtual prototyping of large-scale multi-technical systems. It has the capability of integrating models, which have been created in a variety of languages such as SPICE, ACSL ®, and SABER ®, into… (More)
A simulation model for a hybrid electric vehicle is developed. Permanent magnet synchronous motor is considered for the drive part of the hybrid electric vehicle which comprises three energy sources: (i) a fuel cell, (ii) a battery bank, and (iii) a super capacitor. Rotor-oriented speed controller is designed, and also verified by simulation results, to… (More)
In this paper, we design, and also experimentally verify, a passivity-based controller that forces an induction motor which has significant magnetic saturation to track a time-varying optimal flux trajectory. As a result, we are able to provide close tracking of a time-varying speed/position trajectory that requires close to the maximum torque achievable… (More)
