Design a motor drive system for escalator application using simulink X Development has initiated a shopping mall project at Asgard. This project requires an Adjustable- Speed Drives (ASDs) to operate a few escalator systems within the mall. The project team decides to employs a permanent magnet dc motors in this project. the do motor parameters are listed in Table 2. Assume that a single phase AC mains (utility supply) which is rated at vac2 V, f2 Hz is used to run the motor drive system. Design a dc drive system so that the escalator system is operated in a constant speed of wl.rpm while driven a total load torque of TL Nm. The proposed designed must withstand for 8 % AC supply fluctuation. The armature voltage ripple factor must be less than 2 %. The total harmoniccurrent distortion, THDI must be less than 5% on the ac grid.
