Modelling of Electric Drives using freeFOClib
نویسندگان
چکیده
The freeFOClib (short for “free Field-Oriented Control library”) provides a framework for simulations of electric drives with different application purposes. The library can be used to simply build a field-oriented control system for existing machine models from the Modelica Standard Library, investigate the impact of electric faults (battery faults, inverter faults, machine faults) on a electric drive system, and run simulations to estimate the fuel consumption of hybrid electric vehicles. The library structure and some of its main components are presented. Simulation results of an electric fault are given as an application example of this library. The freeFOClib will be publicly available in Spring 2008.

Application of Speed Estimation Techniques for Induction Motor Drives in Electric Traction Industries and vehicles
Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...

In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...
متن کاملMechanical System Modelling of Robot Dynamics Using a Mass/Pulley Model
The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...
