Implementation of linear elevator with high riding quality based on Scurve profile

The Linear elevators driven by linear motors have recently been widely used because they produce direct motion to transfer people between floors without using ropes, rollers, gears, and counterweights. However, these usually suffer from the production of ripple force when traveling through this makes its application limited. To minimize impact on elevator performance, a smooth transition pattern based minimum jerk profile is proposed. cabin speed controlled via variable frequency driver (VFD), programmed with best V/f get curve in order start stop for constant travel least possible. A three-floor prototype permanent magnet synchronous motor locally designed manufactured lift 25kg payload. result showed that leads reduce about 88% compared driver. proposed model achieved convincing results terms system control, responsiveness, speed, comfortable Silos.
