A gliding depth control method for a biomimetic gliding robotic dolphin includes: obtaining a preset gliding depth and a preset yaw angle; obtaining an estimated velocity by a sliding mode observer based on depth information and inertial navigation information, and obtaining a control quantity of pectoral fins on both sides of the biomimetic gliding robotic dolphin by a yaw controller in combination with the preset yaw angle; obtaining a segmented diving velocity reference trajectory by constructing and segmenting a Bézier curve; obtaining a diving control quantity by a model predictive control method in combination with the estimated velocity; obtaining a target position of a piston through a buoyancy principle, and obtaining a control quantity of the piston according to a current position of the piston; and controlling the biomimetic gliding robotic dolphin to glide based on the control quantity of the piston and the control quantity of the pectoral fins.
