Optimization Design of Hydraulic Press Servo Control Algorithm Based on Fuzzy PID

Hydraulic press is an important molding machine tool. It uses liquid as the working medium to transfer energy to realize various pressure processing processes, and is widely used in aerospace, military, shipbuilding, nuclear power, automobile and other manufacturing fields. Hydraulic press is a large and complex manufacturing equipment operating under extreme conditions such as high pressure, long stroke, large inertia, etc. The position control and operation reliability of its movable crossbeam are critical to product accuracy and equipment safety. Finally, this paper verifies the importance of the fuzzy PID hydraulic press servo control algorithm to the hydraulic start control servo system through simulation experiments, and proves the innovation, feasibility and important value of the design concept in this paper. The fuzzy PID digital control algorithm proposed in this paper can actively overcome the static error of the system, with small lag and no overshoot, and stronger anti-interference ability. Reasonable use of PID regulator not only improves the position control accuracy of the system, but also reduces the performance requirements of other components except the feedback components.
