| contents | This paper presents a comprehensive modeling and control framework for a low-cost multirotor hybrid aerial-aquatic vehicle (MHAUV) capable of seamless air-water transitions. A hybrid dynamics model is proposed to account for the distinct hydrodynamic and aerodynamic forces across three operational zones: aerial, aquatic, and transitional hybrid regions. The model incorporates variable buoyancy, added mass effects, and fluid resistance, with thrust characteristics of submerged propellers analyzed through computational fluid dynamics (CFD) simulations. A hierarchical control strategy is developed, combining twisting sliding mode control (TWSMC) for robust attitude stabilization during medium transitions with cascade PID controllers for precise motion tracking in homogeneous media. Experimental validation using a modified FPV quadrotor prototype demonstrates the effectiveness of the approach, achieving steady-state height errors below 0.1 m and attitude fluctuations under 5° during repeated water-crossing maneuvers. The results highlight the system's adaptability to fluid medium variations while maintaining cost-effectiveness and operational simplicity. |
