Abstract
Nowadays, transportation is a major cause of air pollution. Electric propulsion could replace the internal combustion engines of automobiles and reduce the emission of exhaust gases. The propulsion of an electric vehicle requires the design of an accurate electromagnetic torque estimator and an efficient control system in order to control the speed of the vehicle. This concept is conveyed through this thesis. An electromagnetic torque calculator of an induction motor is designed in the Simulink/Matlab environment through XILINX block sets. The accuracy of the torque estimator is verified using the Field Programmable Gate Array (FPGA). Furthermore, using the proper hardware and software, realistic conclusions about the performance of the electromagnetic torque estimator are drawn.
