In the paper, a controller is designed with the fuzzy control and the special effective velocity compensation signal at the low speed range of the cylinder to overcome the stick-slip effect and obtain the high accuracy. The periodic chargeable compensation signal is designed according to the relationship between the friction force and the velocity, the fl ow rate of the valve, and the dead-zone of the servo valve; and, it's directly added to the conventional fuzzy control signal. The experimental results have shown the effect of the compensation signal, and that the accuracy of the control performance can be obtained and reached to the limit of the resolution of the pulse scale.
