Abstract :
A digital motion control system with primary applications in automatic elevator doors is presented. Digital signal processing methods are used for generating exponential waveforms for the drive motor. The unit keeps track of the actual speed of motion and the corresponding door position. Thus, the time consumed by door motion is minimized, and smooth acceleration and deceleration phases are achieved. The proposed algorithm results have been implemented in an efficient bit-serial ASIC implementation
