Modeling and simulation of electric drive systems using Matlab/Simulink environments

This paper describes a complete modeling and simulation realization on a closed loop induction servomotor drive based on the Matlab/Simulink environment. A simple modeling approach for different types of inverters, based on the dynamic node technique is proposed and a servomotor drive library is described. Based on this library, a speed sensor and/or speed sensorless vector control strategy can be implemented and tested.
