Abstract
In an effort to decrease the rate at which Earth’s climate is changing and reduce the dependency on carbon based fuels. The automobile industry has shifted their focus towards a more sustainable, less harmful energy sources. The emergence of electric vehicles being a result of this shift. The aim of this work is to study the traction chain of an electric vehicle using two controlled static converters DC-DC converter and DC-AC inverter and a permanent magnet synchronous motor (PMSM) with field oriented vector control reinforced with a sliding mode control in order to improve tracking ability and robustness. The voltage source DC/AC converter is considered as a controlled power interface between the electric machine and the output of the DC storage device, the DC/DC converter is used to automatically regulate the battery operating condition in accordance to the profile of the acting on the vehicle wheels, unknown external torque. Particularly, the speed is continuously regulated by the vehicle driver via the pedal while all other regulations for absorbing or regenerating energy are internally controlled. This study is validated by simulation results which are carried out using a dynamic model of the electric vehicle. The analysis and simulations lead to the conclusion that the proposed system is feasible and can be tested on an experimental bench.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
