Elevator Group Control System Based On Fuzzy Control Technology

With the constant increasing in building's height, scale and function, the amount of guests and goods that need transport in the building increases too. So how to rapidly and efficiently transport these guests and goods is an important issue need elevator system dispose. One resolvent is to increase the amount of elevator and enhance elevator's speed. Besides this method, another approach is assigning elevators rationally. In resent years, the technology of intelligent control has developed rapidly. Many famous elevator companies have designed elevator group control system based on technology of intelligent control, and these systems have obtained favorable effect in practical application. Compared with foreign technology, domestic technology of elevator group control has some disparity, which makes the research on elevator group control to decrease these disparity necessarily.By analyzing the characteristic of elevator group control system, the paper explains the feasibility about applying the fuzzy control technique, which is the important embranchment of intelligent control technique, to elevator group control. The paper also designs an elevator group control system based on fuzzy control technique, propose the fuzzy control rules used for rationally assigning elevators and provides the process of fuzzy reasoning. Finally, a simulator model of elevator transportation is established, the fuzzy elevator group control system is simulated by utilizing the simulation system, and the capability of elevator group control system is verified by simulation result.
