Abstract: Aiming at overcoming the shortages of traditional elevator speed control technique which are the relevelling crowl、the running inefficiency of elevator, the basic theory of VVVF elevator speed control system based on desired distance was presented and the specific control procedure was implemented by using embedded system.The results of the experiments indicate that using the new elevator speed control technique can achieve definite relevelling and raise elevator running efficiency.
Key words: desired distance; speed curve control; relevelling crawl; elevator
