Motion Control Keeps Electric Car’s Four Wheels—and Four Motors—on the Road

[font size=5]Motion Control Keeps Electric Car’s Four Wheels—and Four Motors—on the Road[/font]
[font size=3]COLUMBUS, Ohio—It weighs half as much as a sports car, and turns on a dime—so its no surprise that the electric car being developed at Ohio State University needs an exceptional traction and motion control system to keep it on the road.
With four wheels that turn independently, each with its own built-in electric motor and set of batteries, the experimental car is the only one of its kind outside of commercial carmakers’ laboratories.
“It is considered one of the promising future vehicle architectures,” said Junmin Wang, assistant professor of mechanical engineering and Director of the Vehicle Systems and Control Laboratory at Ohio State. “It would make a good in-city car—efficient and maneuverable, with no emissions. Our task is to make a robust control system to keep it safe and reliable.”
In a paper in the January 2013 issue of the journal Control Engineering Practice, his team described the car’s ability to follow a specific trajectory.
