Based on the dynamic model of a supercavitating vehicle and the calculation formula for the complex shape of cavity, the suitable controller was listed. Using the virtual reality technology, the three-dimensional visual scene simulation was completed for the control of a supercavitating vehicle. The research results show that the scene simulation system could simulate the underwater environment, the process of cavity development and dynamic change of sail gesture of the supercavitating vehicle. The results also allow a clear and direct-view for understanding the control effect for supercavitating vehicles. It provides a convenient and effective approach for the control problem of supercavitating vehicles.
