    The PID controller is basically a 2nd order linear filter, while

    the inverted pendulum is a 4th order nonlinear underactuated

    system. It is therefore apparent that PID can only give local

    results to the control of inverted pendulum. The set where

    the PID controller works is actually very narrow here.

    The fuzzy controller is an interpolation of linear controllers,

    and hence could give better performance than for the PID

    controller. However, the underactuated nature of the

    inverted pendulum largely limited the usefulness of the fuzzy

    strategy, unless some modification is enforced.

    FUZZY就是經驗法則

    PID就是精密計算
