The trajectory is based on a set of sequentially-operated piecewise sliding surfaces.
We not only adopt the signed distance as the unique input variable but also present a method of two signed distance for the fuzzy controller, which is called the distance-based fuzzy sliding mode controller (D-FSMC), to control the plant so that the state would follow the sliding surfaces in turn and the parametric uncertainties or disturbances can be reduced effectively.
By using the two signed distance for the fuzzy controller, the response of the tracking error will be small than that of the unique input variable.
Furthermore, we can explicitly calculate the total tracking time for each surface including the hitting time.
It is shown that the stability of the control system is guaranteed in the Lyapunov sense.
Finally, an inverted pendulum control problem subject to external disturbance is simulated to demonstrate the validity of the proposed D-FSMC.
