Asymmetric fuzzy PID control for pneumatic position control system
气动位置伺服系统的非对称模糊PID控制

For asymmetric physical structure and friction characteristic of single rod cylinder, a new fuzzy PID algorithm of asymmetric fuzzy strategy for pneumatic position control system was presented. It could effectively solve the difficult problems, which were mainly caused by asymmetric structure and different friction characteristics in two directions. The experimental results proved that, with this strategy, the dynamic performance of the system could be much improved. The system obtained desired percentage overshoot and repeatability in both transient and steady-state responses.
