In this paper, linear elevator driven by permanent magnet synchronous linear motor (PMLSM) is used in fuzzy PID control method, in which it is to adopt the magnetic guidance system to control the PMLSM gap which changed frequently, and it can impact the vertical thrust and control the level vibration and noise in the process of start, operation, and stop to make passenger comfortable. Matlab modeling...
The attraction of neural networks is that they are best suited to solving the problems that are the most difficult to solve by traditional computational methods. BP neural network is widely used in many fields. In this paper, analysed the control requirements of servo control system, combined control characteristics of neural network and PID based on mathematical model of permanent magnet linear synchronous...
The elevator cab will vibrate because of the edge effect in the linear elevators that is driven by the permanent magnet linear synchronous motor (PMLSM). This article adopts correction factor fuzzy - PID control method in order to solve the vibration of elevator cab. The fuzzy control is not completely dependent on the mathematics model, but the fuzzy rules are obtained by experiences of authors or...
With the rapid development of super-skyscrapers, the elevator driven by permanent magnet linear synchronous motor (PMLSM) is one type of rope-less elevator and is more feasible among the rope-less elevators for actual in the near future. But the edge effect of permanent magnet linear motor results in the vibration of elevator cab. And the high air gaps between primary windings and second windings...
