Torpedo is an autonomous underwater vehicle. Its motion control system is complicated and its modeling is difficult. In this paper, the mathematical model of the torpedo dynamics and kinematics is described firstly. The control system mathematical model of the torpedo is described. The methods for both building graphic model and realizing the S functions are discussed in details, and the Simulink graphic model for torpedo control system is created. Finally, the simulation method for torpedo control system is given, and the simulation results are discussed and analyzed. The simulation results show that the combination of Simulink and C/C++ is flexible, effective and powerful in modeling for torpedo and other complicated vehicles.
