空気圧シリンダにおける位置センサを使用しない位置制御

―等温過程を想定した定常位置偏差の検討―

In a precise positioning control of a pneumatic cylinder, a position sensor is essential to implement a feedback system; however, it also leads to an increase in the total cost since the high-resolution positioning sensor is generally expensive. Cost reduction is therefore an important factor for the further market expansion of pneumatic actuators against other types of actuators. In this research, we propose a position control system that does not use position sensors, based on the state equation of air, and verify its practicality by demonstrating the basic control performance.
