Stabilization of an inverted pendulum cart with a balancing mechanism by consistent trajectories in acceleration behavior

New personal vehicles are required in current society because of necessity of low-carbon system. At present, most personal vehicles require a driver to have a certain level of physical ability. Low-carbon personal vehicles should, however, be made available to people with lower levels of physical ability, such as the elderly. The present paper therefore proposes an inverted pendulum cart that incorporates a balancing mechanism with actuating a seated driver. In the case of the proposed inverted pendulum cart, since the driver does not have to be able to maintain balance in order to cause the vehicle to accelerate, the proposed cart can be used by almost anyone. In addition, a control method using both input generated by desired acceleration trajectories and dynamics-canceling input is proposed. The effectiveness of the proposed control method is confirmed by simulation.
