The invention discloses a pressure experiment device and a pressure tracking method for an underwater mobile platform, belongs to the technical field of marine equipment detection, is used for a pressure detection test of underwater equipment, and comprises a pressure control end, a pressure supply end, a pressure experiment module and a monitoring terminal; during working, an oil quantity value of equipment to be tested is transmitted to the model calculation terminal through the serial port communication unit, the model calculation terminal calculates a depth value through a kinetic model of the equipment to be tested, the pressure sensor collects a pressure value in the pressure experiment module and sends the pressure value to the pressure collection unit, and the PID control algorithm compares the input depth value with the pressure value in real time. And if the pressure value in the pressure experiment module is not matched with the depth value of the to-be-tested equipment, the current acquisition control unit and the switch control unit adjust the pressure supply end. Through a PID control algorithm, the pressure experiment module tracks the depth value calculated by the model, and completely simulates the pressure change of the to-be-tested equipment in underwater autonomous operation.
