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.
Smart components-based servo pneumatic actuation systems
Abstract Pneumatic drives are the most widely used form of industrial actuation system. However, research in relevant areas is very limited, often carried out, if at all, in isolated environments. There is a lack of strategic thinking and tools, which can enable developments to go forward in an efficient manner. In recognising the advancements in PC-technology, fieldbus systems, microprocessors and computing technologies, the authors advocate the concept of smart components-based servo pneumatic actuation systems. The paper expands on the components-based nature of pneumatic drive systems to identify design templates for smart valves, smart sensors, smart actuators, etc. The development of components-based pneumatic drive systems is considered in the context of a recently completed UK EPSRC funded research project on high speed servo-pneumatic actuation, addressing issues such as simulation tools, algorithm development, sizing, tuning, installation and commissioning. A high speed pneumatically-driven gantry pick-and-place handling system with novel design features is presented to demonstrate the capability and attributes of pneumatic drives for more sophisticated applications.
Commissioning of a servo-pneumatic system for timing and profile control in a high speed food packaging application
Servo-pneumatic systems can provide an alternative to the use of conventional binary pneumatic drives and servo-electric systems. However, a migration path needs to be identified for this to become a practical reality in industry. In this paper, methods for employing pneumatic drives in applications with timing and profile control requirements are investigated. This study is based on a high speed food packaging machine used in industry which currently employs on/off pneumatic actuation. The paper illustrates how advanced features of modem motion controllers can be utilized and what control functions are required to exploit the potential of servo-pneumatic actuation. It also serves to illustrate how pneumatic servos may provide an effective alternative to the use of electric servo mechanisms in some applications. The contribution of this paper is significant in the sense that it illustrates the process of applying servo-pneumatic systems which are currently not well established in industry. The paper shoul...
