Synchronization Control Simulation for Pneumatic Elevator Based on AMESim
For the research of simulation of synchronization control for pneumatic elevator, a model is builtin AMESim software. The simulations are used to research the impact of synchronous control strategy. The simulation results show that there are good synchronizing effects by applying pneumatic proportional technology and synchronization control with master-slave mode based on PID control. Some theoretical guidance is provided for synchronization control of real system.
Implementation of an Automated Vacuum Elevator System
Pneumatic vacuum elevator (PVE) has become a popular choice for our homes and low-rise buildings in recent years. The Pneumatic vacuum elevator represents a new concept evolved from the idea of pressed air applied in the pneumatic elevator replaced by a vacuum air idea. The pneumatic vacuum elevator is able to transport people between building floors without using any cables, counterweight, or pulleys. A simple and low cost construction and implementation for an Electro-pneumatic vacuum elevator system prototype is presented in this paper. The elevator system prototype is constructed with three floors to elevate a maximum load of 6kg. Programmable Logic Controller (PLC) of (LS\GLOFA-G7M-DR30U) series with (16) inputs and (12) outputs programmed with Ladder diagram software is used for the fully automated the elevator system. The idea of the proposed elevator system may be predicted to be widely spread in the low-rise residential buildings.
Application and Design Trends of “intelligent” Servo Pneumatics
Abstract New initiatives in designing and applying “intelligent” servo pneumatic cylinders and motors emerged in last decade or so. However, a severe lack of confidence and knowledge still prevails in industry in the selection of servo pneumatics as an alternative to electric drive technology particularly for advaced applications. This paper aims to promote the application and public appreciation of servo pneumatic systems. The paper reviews the inherent properties and performance capabilities of servo pneumatic drives. Applications considered to be appropriate for applying servo pneumatics will be investigated through the analysis of a selected example
