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 کاملResearch on Pneumatic Servo Control for Double-Cylinder Collaborative Loading Based on Neural Network
The pneumatic control system for double-cylinder collaborative loading is extensively applied in the industry. However, compared to the hydraulic system, it is difficult for the pneumatic system for double-cylinder collaborative loading to get satisfactory effect due to strong non-linearity and low rigidity. To improve robustness of the double-cylinder collaborative loading system and increase ...
متن کاملAsymmetric Fuzzy Control of a Positive and Negative Pneumatic Pressure Servo System
The pneumatic pressure control systems have been used in some fields. However, the researches on pneumatic pressure control mainly focus on constant pressure regulation. Poor dynamic characteristics and strong nonlinearity of such systems limit its application in the field of pressure tracking control. In order to meet the demand of generating dynamic pressure signal in the application of the h...
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 ...
