Modeling and simulation of electrical drives using MATLAB/Simulink and Power System Blockset

This paper presents a unified method for modeling and simulation of electrical drives using state-space formulation in MATLAB/Simulink. The proposed method has been successfully implemented in a simulation package called "Power System Blockset" (PSB) for use in MATLAB/Simulink environment. The principle of the modeling and simulation method is presented and the PSB operation is described. Application examples including a DC brushless motor drive and a direct torque control (DTC) induction motor drive are presented. Simulation results obtained with the PSB are presented to illustrate its possibilities.
