Abstract: In the process of rebuilding the control system for a large water-press machine,a servo control system is designed by integrating sliding mode control with fuzzy logic control(FSMC),as the hydraulic servo system is characteristic of large parameter variations and external disturbance.By introducing a continuous fuzzy layer in the sliding mode control,the FSMC reduces dithering phenomenon effectively and produces a perfect result in the manufacturing.It excels the conventional PID control.

Key words: SMC； fuzzy control； water press test machine； hydraulic servo system；
