Due to the two rounds of two-wheeled self-balancing electric vehicle structure, making it at the
top and Fulcrum below the center of gravity, in non-control (or static) next to an unstable system.
However, you can use inverted pendulum system control theory, by microprocessor control so that
it can be as stable as the pendulum in a balanced position, and in a State of balance in accordance
with the user's instructions to function properly. Two-wheeled self-balancing electric vehicle is
actually level linear inverted pendulum and the combination of rotational inverted pendulum and
its control principles consistent with the pendulum. More figuratively, self-balancing electric
vehicle work more like the walking process. For the people, when the body's Center of gravity when
you lean forward and lost his balance, through their own senses to feel the body's tilt (angle),
so he can make a reaction – a step forward to prevent his fall to the ground. If the body is
leaning forward, in order to maintain the balance, people will go step by step. Therefore, if two
motor-driven wheel adult legs, plus be able to measure body relative to the size and speed of the
water level angle sensors, and finally through the microprocessor control the effects of the body
balance can be achieved. So when people stand when in the car, just drive the car with the body
forward (or backward) can achieve the electric manned forward (or backward).
