   Computer Aided Educatio of Power Electronics using Object Oriented Modeling Language
By V. V. Sastry; T.V. Sivakumar [View]
[Download]

Abstract: This paper focuses on various issues related with the selection of a tool for Power Electronics (PE) education. PE education using a PC based object oriented modeling language namely DYnamic MOdeling LAnguage (DYMOLA) and Advanced Continuos Simulation Language (ACSL) is discussed. With the proposed tools, modeling environment is totally decoupled from the simulation environment, which is the state of the art. To illustrate the elegance of the proposed approach, two examples namely a tolerance band controller based DC-DC converter and a closed loop V/f slip regulated Induction Machine (IM) drive are presented.

Abstract: In this paper an experimental interactive workbench for control of variable speed induction motor drives for electrical engineering laboratories, is presented. With this system, first the student can in a friendly way from the PC with a multimedia software, simulate the operation of an electric locomotive running between two railway stations, and in an interactive way, learn the different components of the drive, as well as calculate and simulate their behaviour. On the other hand, a PWM experimental drive of induction motor variable speed, controlled by a high resolution Digital Signal Processor device, permits the student to try and analyse various control strategies as well as the operation with different parameters values. These changes can be programmed directly from the Personal Computer, using a friendly graphic interface. For all these reasons, this experimental product, can be a useful tool to assist students with their learning endeavours and their own training in the practical use and knowledge on induction motor speed and torque control drives, in the classical scalar control mode, as well as vector control mode.

   Teaching of AC Motor Field orientation Principles Enhanced with the TCad Circuit Simulator
By P.J. Chrzan; R. Szczesny [View]
[Download]

Abstract: This paper describes usefulness of the TCad circuit simulator as an education tool for ac motor field oriented control teaching. In the example of direct rotor field oriented control (RFOC) of induction machine, a constant gain observer design is studied at observer parameter estimation errors (+/- 50%). Parameter sensitivity analysis is used for evaluation of observer flux component errors and their influence on field orientation performance. Functionality of the TCad simulator is demonstrated by modelling power electronic, machine and control tasks of the drive. This global model is used to verify the RFOC observer based drive system at normal and detuned conditions.

   XSIM: Software Package for Simulation of Induction Machines
By F. Barrero; R. Millán; P.G. Sánchez; M. Sánchez; L.G. Franquelo [View]
[Download]

Abstract: This paper presents a software package for simulation of induction machines useful for training and computed aided education. The software collects the experiences of several years of study and research in the fields of control of induction machines, including vector control, space-vector and pulse width modulation techniques and fuzzy logic based control. The system has been designed in such a way that presents the machine as an induction motor with different loads (mechanical and electrical) or as an induction generator moved by a user definable torque. By incorporating the different procedures in a single package and by adding a user friendly interface and plot capabilities, a power tool has been obtained useful to introduce students to the most up-to-date solutions in the field of vector control of induction machines.
