The invention provides an autonomous suspended particulate matter capturing navigation system and method.The system is composed of a collecting module and a power module, the collecting module is arranged on the power module and is of an eccentric funnel structure, and a steering engine controls a collecting bottle to rotate along the axis of a supporting disc as needed; and collecting a time series of suspended particulate matter samples. The power module integrates a horizontal propeller, a vertical propeller, a control surface and a buoyancy adjusting system, response equations of the propellers, the control surface and the buoyancy adjusting system are obtained by using an advanced system identification algorithm calibrated by a laboratory, and a high-robustness algorithm is designed based on a passive control theory so as to improve the stability and three-dimensional maneuverability of the control system. The motion control algorithm is implemented by a low-power-consumption embedded processor and provides rapid and accurate pose adjustment response, so that the capability of carrying out large-range rapid maneuvering in a three-dimensional space is achieved to adapt to variable hydrological environments and execute complex sampling tasks.
