This invention discloses a method for controlling the downward speed deviation of a hydraulic press slide, belonging to the field of hydraulic press control technology. The method first collects real-time signals of slide position, main cylinder pressure, and oil temperature, and calculates the speed deviation. When the speed deviation continuously exceeds the limit, the system automatically switches from basic PID control to adaptive fuzzy PID control mode. In this mode, the system comprehensively considers the speed deviation, its rate of change, and pressure signals, determines the dominant disturbance type online according to preset rules, and generates targeted compensation commands accordingly. Through a multi-disturbance coordination strategy, the commands are output in an orderly manner to actuators such as proportional valves, cooling valves, and hydraulic pumps. The system monitors the speed deviation in a closed loop, achieving automatic mode recovery or abnormal protection. This invention achieves accurate identification and dynamic compensation of multiple disturbances, significantly improving the control accuracy, anti-interference capability, and system intelligence level of the slide speed.
