Concept of Improving Positioning of Pneumatic Drive as Drive of Manipulator

The paper presents a mathematical model of pneumatic actuator based on a piston rod air double acting cylinder. The model was solved using MATLAB Simulink. The results of model simulations were compared with experimental results and the drive control system was proposed. The article also includes the concept of the control system of pneumatic drive equipped with electromagnetic brake. The application of the brake is to increase the accuracy of the positioning of the actuator piston, which in turn will enable the use of this drive in the structure of parallel kinematic manipulator. Presented research provides preliminary data for assessment of the improvement of air cylinder control.
