摘要：
Fuzzy controllers with variable universe of discourse (VUD) have been applied in many fields of intelligent controlling because of their high-accuracy performance. This paper provides a lookup table method to design backing-up fuzzy controllers based on VUD. By setting a set of random start points, input-output data pairs are obtained using test-driving method. One data pair defines one fuzzy rule and also assigns the strength of every fuzzy rule. Conflicting fuzzy rule groups are integrated into one fuzzy rule by selecting the one with the maximum strength. A fuzzy rule table is built by the fuzzy rules deduced from input-output data pairs. Simulation experiments show that the VUD fuzzy controller outperforms the general fuzzy controller in accuracy at the final position of the parking lot.

摘要：
Fuzzy controllers with variable universe of discourse are capable of receiving high-accuracy due to the online operation of expansion-contraction factors. In this paper, an algorithm is presented for variable universe fuzzy control algorithm which is now popular in the control engineering. The parameter in the expansion-contraction factors is discussed in detail on various systems with unstable poles, unstable zeros or both unstable poles and zeros. Simulation examples show that the change of the parameter has significant effect on the system response. At the same time, we obtain the optimal value of the parameter in expansion-contraction factors.
