Abstract: This paper concerns on implementation of a fuzzy logic controller (FLC) on a Field-programmable Gate Array (FPGA) system for intelligent control of elevator system. The search for an intelligent group controller that can satisfy multicriteria requiements of an elevator group control system has become a great challenge for researchers. This proposed approach is based on algorithm which is developed to reduce the amount of computation required by focusing only on the relevant rules and ignoring those which are irrelevant to the condition for better performance of the group of elevator system. Simulation was carried out by considering two inputs i.e. elevator car distance and number of stops. Based on these data the Fuzzy Controller can calculate the Performance Index (PI) of each elevator car. And the car which has maximum PI gives the answer to the hall calls. This would facillitate reducing the average waiting time (AWT) of the passenger.
