Self-sustaining driving control of two-wheeled vehicle by using gyro-actuator

Gyro is not only used as a sensor but also used as an actuator. In the beginning of 20Th century, the gyro monorail using a gyro-actuator which was controlled by manual operation was proposed. In 1970's, the research on a gyro bike was reported. However, a standstill was only confirmed in it. On the other hand, the self-sustaining control of two-wheeled vehicles by using an inertia rotor are reported recently. However, it is difficult to make a large vehicle because this inertia rotor system has only a smaller power as compared with that using the gyro actuator which can obtain a larger power. The modeling is needed for the control system design of the vehicle with a gyro actuator. In this paper, first, positions, angles, and angular velocities are calculated from 3rd link system, then the model for the two-wheeled vehicle with a gyro actuator is made by using Lagrange equation, next the control system is designed by the Ricatti equation, finally the effects of this theory are confirmed by experiments.
