A novel control for linear elevator based on reference model sliding model

To the permanent magnet linear synchronous motor(PMLSM) for vertical hoist system, discontinuous primary PMLSM was adopted. In order to achieve anticipated performances and improved system dynamics, a novel compound control scheme for linear elevator driving by PMLSM with reference model sliding mode control is presented, which integrates advantages of sliding mode control and reference model control. The simulation results show that this method can overcome external disturbances and obtain good performance compared with traditional PID control. So the elevator cab will become more comfortable and suitable for people.
