Precise Position Control of a Pneumatic Servo Table System Consideration Dynamic Characteristics of Pneumatic Servo Valves
The performance of the pneumatic servo systems improved greatly as the pneumatic servo valves became commercially available in the late 1980s. At present, one of the best pneumatic servo valves has a dynamic response of 100 Hz and a spool position accuracy of 2% to the full stroke. By using these pneumatic servo valves, the precise position control by the pneumatic servo system has entered a pr...
متن کاملControl System Design of a Pneumatic Servo System
Pneumatic servo systems are applied in several industrial applications and have also been studied extensively for the purposes of compensating the nonlinearity of pneumatic servo systems and improving the controllability with robust control. In their control system design, the transfer function of a pneumatic servo system has been a third-order time lag system, based on the assumption that serv...
متن کاملFuzzy logic positioning system of electro-pneumatic servo-drive
Development of automation and robotization in manufacturing process stimulates interest in pneumatic servo-systems whose advantages include low manufacturing costs, high dynamics and reliability (Situm et al., 2004). Unsatisfactory positioning accuracy of multiaxis pneumatic servosytems considerably reduces their application in manipulating machines, manipulators and robots. Rapid advance in pa...
متن کاملEnergy Saving Control for Pneumatic Servo Systems
This paperproposes an energy saving approach io the control ofpneumaiic servo systems. The control meihodology is presenied, followed by experimental results ihai indicate significani energetic savings and esseniially no compromise in tracking performance relative to a purely active approach. Speci$cally, experiments indicaie an energv savings of 10 to 46% (depending on the desired tracking fre...
متن کاملDead Zone Compensation in Pneumatic Servo Systems
This paper presents an approach for dead zone compensation in pneumatic position servo systems. The dead zone is an inherent nonlinearity in pneumatic servovalves, where for a range of input control values, the valve gives no output flow. Although pneumatic actuators are very common in industry, they have limitations in servo pneumatic applications that are caused by typical non-linearities of ...
