Design and control of new intelligent pneumatic cylinder for intelligent chair tool application

This research develops a new intelligent pneumatic actuator consisting of five extensive elements in a single device combining software and hardware architecture design. A micro optical encoder chip is used to detect cylinder rod position by reading constructed laser strips guide rod whereas a pressure sensor is used to detect the chamber pressure reading. 2 unit valves of two ports two positions are used to control the cylinder movements by manipulating PWM cycles. These hardware parts are controlled using designed algorithms in PSoC microcontroller. Two control approaches have been tested for the function ability of the actuator which are servo position control and pressure control. The results show that, the actuator is possible to be used for Intelligent Chair Tool application.
