In this paper,a continuous multi-speed control scheme for elevator is proposed.The precise locating is implemented by counting high frequency pulses which are generated by optical rotary encoder.The continuous multi-speed control is implemented by PWM speed control as well.The ideal speed and acceleration are determined by on-site testing.The floor positions,flat bed positions and speed switching point are calculated manually.The real-time requirement of precise locating and calling response are met in this scheme.
