An Assist Control using an Electric Motor for One-wheel cart

In recent years, the number of farmers in Japan has been declining and the population is aging. The electrification of the agricultural machines is one of solutions to reduce the work load of elder workers. However, electric powered one-wheel carts in current market on the market have the problem that they require accelerator operation. In order to solve this problem, this paper proposes an assist control for electric powered one-wheel cart implemented with inertia simulator. An inertia simulator can give the motor torque assist which achieves equivalently the no load condition for the operator. The proposed system was verified by simulation and the prototype one-wheel cart was designed.
