Abstract :
Electromagnetic elevator can achieve zero-touch between elevator car and guide rail. “Eight-Maglev” topological structure is used to electromagnetic guidance system. The influence of the load disturbances, parametric variations and uncertainty of electromagnetic guiding actuator for linear elevator is considered in this paper, fast tracking strong robustness and effectively restrain horizontal vibration of the car is realized by using H∞ robust control. The simulation results show that H∞ controller is of more strong robustness and anti-disturbance ability than PID controller.
