Background<\/span><\/span><\/p>\n<hr \/>\n<p style=\"text-align: justify\"><span style=\"font-size: 14px\">The significance of vehicle electrification is far beyond replacing engines and oil tanks with electric motors and batteries. Especially, the motion of EVs is provided by wheels driven by electric motors. EVs are actually very typical mechatronic systems. In term of motion control, the uniqued advantages of electric motors over internal combustion engines and hydraulic braking systems can be summarized as follows:<\/span><\/p>\n<ul>\n<li><span style=\"font-size: 14px\">Far less complex dynamic model<\/span><\/li>\n<li><span style=\"font-size: 14px\">Faster torque response in milliseconds<\/span><\/li>\n<li><span style=\"font-size: 14px\">Easiness in obtaining accurate torque feedback<\/span><\/li>\n<li><span style=\"font-size: 14px\">Capability of generating both traction and braking forces<\/span><\/li>\n<li><span style=\"font-size: 14px\">Easiness in implementing distributed in-wheel-motor system<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify\"><span style=\"font-size: 14px\">Consequently, the fundamental difference between electric motors and engines is that the electric motors can be used not only for mobile propulsion, but also as actuators and sensors due to their fast and accurate responses and relatively simple dynamic models. By making full use of the above unique advantages, advanced dynamics of EVs could be achieved with flexible and simplified configurations because the electric motors may replace the most of conventional vehicle dynamics control actuators.<\/span><\/p>\n<p><span style=\"font-size: 18px\">2.
