Traction Control in Electric Vehicles

Transportation sector is one of the biggest industrial sectors nowadays. Since the development of the internal combustion engine and its application to the transportation sector, people are becoming dependent on a more economic and comfortable way of traveling. However, besides all the benefits that combustion engines can provide, the abusive use of fossil fuels, its constant increase of price and recent environmental concerns led to a new form of mobility, supported on a technology already used in the past: the electric motor. Having this in consideration, this book aims at analyzing and discussing the control domain in electric mobility concerning the permanent magnet synchronous motors, in particular an application of a 150kW motor for an electric bus. It is presented the design of the controller that drives the motor, allowing its driving and braking, with the ability to regenerate braking energy for recharging the batteries. Also, the system is capable of working without speed or position sensors.
