Abstract:Through the establishment of aerodynamic model and the joint simulation,cylinder crawling at low speed and the
source of location error were discussed. Air source pressure,mass of load,and friction difference influence on cylinder
crawling were analyzed. System is controlled by single neuron PID and adding vibrating signal instead of traditional PID. The
results show that big air source pressure,small mass of load,and small difference of static and dynamic friction can help
prevent the crawling. And system crawling was solved using single neuron and vibrating signals. It is confirmed that
positioning accuracy was improved from ±0.61mm to ±0.25mm by simulation. It provided a more ideal control strategy for
cylinder smooth running at low speed.
