CONTROL OF A PERSONAL TRANSPORTER

摘要

Methods for controlling a motorized balancing transporter that has two wheels in contact with the ground in normal operation. Upon detection of a fault condition, a control variable is adjusted at a specified increment in the direction of a goal value until the control variable equals the goal value. A user is afforded accelerated access to operation of the balancing transporter by first initializing a single-axis stabilizer, and, while intializing a 3-axis stabilizer, allowing operation of the transporter, and then completing initialization of the 3-axis stabilizer. Traction is maintained between wheels of a transporter and an underlying surface by comparing acceleration of a wheel with a specified pre-set value and incrementally reducing the torque applied to the wheel based on the existence of slip condition, with the slip condition cleared on the basis of a determined value of a dynamic characteristic of the wheel such as the inverse moment of inertia.
