Modular approach for simulating electrical drive systems with Matlab/Simulink

Variable speed electrical drives are very complex systems which makes difficult their study when detailed analysis is required along with their global behavior. With the help of advanced software tools for circuit analysis and for modeling a drive system following a modular approach, it becomes much easier to study those complex systems. This paper presents a methodology for use with Matlab/Simulink environment in which the main parts of an electrical drive are modeled as interlinked functional blocks. The complete drive system (from supply to mechanical load) is analysed as a set of independent but integrated modules
