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.
