“…This is mainly caused by air compressibility and friction in the valve [2] and actuator, which make the pump-lineactuator dynamic system highly nonlinear. Novel hardware [3], [4] and pneumatic-servo control [5], [6] solutions have been proposed to cope with these problems, and impressive results have been achieved in force control [7], [8] and speed regulation [9]. Nevertheless, these complex solutions require special care, and so most practical applications are still limited to unregulated pneumatic motion.…”

This paper presents a new type of pneumatic motor, a pneumatic step motor (PneuStep). Directional rotary motion of discrete displacement is achieved by sequentially pressurizing the three ports of the motor. Pulsed pressure waves are generated by a remote pneumatic distributor. The motor assembly includes a motor, gearhead, and incremental position encoder in a compact, central bore construction. A special electronic driver is used to control the new motor with electric stepper indexers and standard motion control cards. The motor accepts open-loop step operation as well as closed-loop control with position feedback from the enclosed sensor. A special control feature is implemented to adapt classic control algorithms to the new motor, and is experimentally validated. The speed performance of the motor degrades with the length of the pneumatic hoses between the distributor and motor. Experimental results are presented to reveal this behavior and set the expectation level. Nevertheless, the stepper achieves easily controllable precise motion unlike other pneumatic motors. The motor was designed to be compatible with magnetic resonance medical imaging equipment, for actuating an image-guided intervention robot, for medical applications. For this reason, the motors were entirely made of nonmagnetic and dielectric materials such as plastics, ceramics, and rubbers. Encoding was performed with fiber optics, so that the motors are electricity free, exclusively using pressure and light. PneuStep is readily applicable to other pneumatic or hydraulic precision-motion applications.

The pneumatic counterweight method is a suitable counterweight method used for machine tool owing to its high speed and force capacity, combined with low price and clean operation. However, the preset pressure cannot be hold at higher traveling rate if the conventional pneumatic counterweight is applied. In this study, rather than using the conventional pressure compensation method, the active pressure control method was designed as an alternative to the pneumatic counterweight driven by a linear motor. The fuzzy sliding mode controller was designed and implemented for regulating the pressure using the servo valve. The experimental results demonstrate that the variation of the pressure in the pneumatic cylinder can be hold within the range ±15 kPa by using active pressure control method.

Some of these can be provide important advantages are easy and ready availability of air, very simple construction, clean and low cost [2,3]. Also, pneumatic systems are especially can be easily maintenance and provide high speed control action with high power to weight ratio [4].…”

This work is concerned with the design and implementation of position control electro-pneumatic system using ON/OFF solenoid directional control valves. To realize this approach, it's required to set up a laboratory mechanical test rig involving pneumatic, mechanical and electrical apparatus. The proposed design of control system includes electro-pneumatic circuit interfacing with position sensor, especially used in this work to detect the distance of the rod of pneumatic actuator. The suggested model mainly consists of double acting pneumatic cylinder, two solenoid directional valves, two position sensors and electrical control circuit. The simulation process of the employ system has been done with using MATLAB software and the obtained theoretical as well as practical results have been compared to investigate the pest performance. The obtained results showed that the proposed system can be applied with high accuracy and efficiency.
