1.1 HISTORICAL CONTEXT
ThesimulationofinductionmotorsusingLabVIEWhasits roots in the evolution of motor analysis and control methodologies. Initially, motor modeling relied on mathematical equations and analog tools, focusing on steady-stateandtransientperformance.Withtheadventof digital computing in the 1970s, numerical simulations becamemoreaccessible,andlanguageslikeFORTRANand MATLAB gained prominence in motor analysis, enabling more precise modeling of dynamic behaviors.
