Kind Code:
A
Abstract:
PURPOSE:To prevent the deterioration in the fine control property, i.e., an original. advantage of the fuzzy control by changing a rule based on the remaining distance data value. CONSTITUTION:A rule changing part 13 changes the connection to a membership function processing pert (incl. THEN arithmetic part) which shows the drive information displacement variables (+ E) end (-AE) with the smell end large remaining distances respectively. The membership functions MF 14 (smell remaining distance) and MF 15 (low speed) show a smell remaining distance and a low speed respectively. In a rule changing state, the MF 14 and MF 15 ere connected to a THEN arithmetic part a and a THEN arithmetic part 7 respectively according to the value of the remaining distance. Then an MF 3 (large remaining distance) is connected to the part 7 together with an MF 4 (high speed) connected to the part 8 respectively when the remaining distance is large. As a result, the fine fuzzy control is always secured.
