“…Adopting the approach of physical network modeling technique followed by many researches [11][12][13][14][15] , the dynamic equations for the pneumatic system in this research have been modeled and simulated using Matlab® Simscape toolboxes and discussed in details in [1] . The model has been validated by comparing the predicted dynamic behaviour of the system to the experimentally measured one.…”

Pneumatic cylinders are used as actuators for modern automated systems in many industries applications for their numerous advantages. Basically, those applications are implemented using components such as proportional and servo pneumatic control valves that are relatively expensive because of their high accuracy even in applications that do not require such high accuracy. Recently, binary (on/off) solenoid directional control valves (DCVs) have been used to replace many of the expensive components and consequently reduce the system cost with achieving acceptable accuracy. This paper presents a control

“…For the models presented above, the algorithm will work in a closed loop and the implementation method will depend on the chosen model. [6] Solutions that can be used include embedded systems, programmable logic controller, industrial computers, PCs and so on. Their programming can be done in a very large number of languages, depending on the platform and hardware resources -Assembly, C/C++, Python, Java, graphical languages, or high-level languages specific to a particular equipment (STL, LDR, G, etc.).…”

This article presents the hardware structure for a new type of closed loop positioning system using pneumatic energy. In brief, when the mobile subassembly of the system is about to reach a targeted position its speed is controlled by the small-sized pneumatic electro valves, which are commanded in modulated pulses. Here, we developed an electronic control system of which memory has a specially designed algorithm. In addition, the pneumatic engine has a specific construction that integrates a transducer of position as well as a braking system. The proposed mechatronic system is described by good positioning accuracy and low cost.

“…В настоящие время производители позиционных приводов (Camozzi, SMC, Festo, Pneumax, Air torque), как правило, обеспечивают торможение и позиционирование с использованием внутренних тормозных устройств, управляющих потоками сжатого воздуха [1,2,3,4]. Основные недостатки таких систем связаны со сложностями управления потоками сжатого воздуха (как правило, нестационарно сжатыми) из-за изменяющихся свойств и параметров состояния рабочей среды.…”

The work objective is to introduce a design of the automated pneumatic drive (APD) with an external braking gear. It is a controlled pneumo-mechanic brake providing the process time reduction, the positioning accuracy increase, and the reliable positioning of the stop mechanism in the setpoints. The application of the prototype drive with the automated measurement complex creates conditions for the oscillographic testing of the positioning process in real time and space, and it also provides reliable experiment results. The authors have created a special stand - a model of the proposed drive that allows investigating the effect of its positional accuracy under different parameters of its operation. Kinematic and power characteristics of the drive in the automatic operation by the compressed air flow are identified. The effect of the positioning speed and the brake control pressure on the drive accuracy is resulted. Recommendations for the development of real positional drives with increased performance and positioning accuracy are formulated. It is found that the introduction of an outer braking device - the controlled pneumo-mechanic brake - improves the positioning accuracy of these drives by 1,25-2,25 times.
