Advanced Redundancy Technology for a Drive System Using In-Wheel Motors
نویسندگان
چکیده
In electric vehicles that use in-wheel motors, the right and left traction forces become unbalanced if a motor malfunctions by motor lock or loss of traction, generating yaw moment. Control methods were designed to reduce this effect by stopping the motor output on the opposite side of the same axle. By using a prototype “Eliica” car, the maximum yaw rate and lateral acceleration were compared for a breakdown of one motor with the results from the “Sensitivity to lateral wind” indicated in Z108-76 of the Japanese Automobile Standards Organization. Under redundancy control, the test results were confirmed to be below the tolerance limits

Holonomic Control of a robot with an omni- directional drive
This paper shows how to control a robot with omnidirectional wheels, using as example robots with four motors, and generalizing to n motors. More than three wheels provide redundancy: many combinations of motors speeds can provide the same Euclidean movement. Since the system is over-determined, we show how to compute a set of consistent and optimal motor forces and speeds using the pseudoinver...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
