A fuzzy control algorithm of asymmetric fuzzy strategy is introduced for a pneumatic position system. It can effectively solve the problems of single rod cylinders that are mainly caused by asymmetric structures and different friction characteristics in two directions. On the basis of this algorithm, a traditional PID control is used to improve the dynamic performance. Furthermore, a new asymmetric fuzzy PID control with the α factor is advanced to improve the self-adaptability and robustness of the system....
