“…Supercavitation drag reduction technology has been extensively researched due to its notable advantages in achieving high rates of drag reduction and minimal structural requirements for the vehicle. By creating a stable gas phase surrounding the vehicle, the rate of drag reduction can exceed 90% [19]. Supercavitation can be categorized into natural supercavitation and artificial ventilation supercavitation.…”

An unmanned underwater vehicle (UUV) powered by a compressed air power system is proposed to address challenges for battery/motor-powered vehicles under high-speed navigation, long endurance, and high mobility. These vehicles actively utilize supercavitation drag reduction by the exhausted gas from the compressed air power system. MATLAB/Simulink and FLUENT are used to establish theoretical models of the compressed air power system and ventilation supercavitation. The relationship between system power and navigation resistance is examined with different air flows, along with a comparison of endurance of different power vehicles at various speeds. The issue of the endurance-enhancing effect of supercavitation at high speed is investigated. The results demonstrate that increasing the air flow leads to higher power and reduced navigation resistance, and there is a balance between them. Furthermore, compared to the battery-powered vehicles with equal energy storage capacity, the compressed air power system shows 210.08% to 458.20% longer endurance times at speeds of 30 kn to 60 kn. Similarly, considering equal energy storage mass, it achieves 42.02% to 148.96% longer endurance times at high speeds (30 kn to 60 kn). The integration of supercavitation and air-powered systems can greatly enhance the endurance and maneuverability of the vehicle at high speeds while ensuring a compact system structure. The investigations could offer valuable ideas for the development and application of compressed air power systems for UUV at 30 kn to 60 kn or higher maneuvering.

“…Aiming at the time lag resulted by network transmission and parameter uncertainty engendered by system aging, Xu et al 24 considered isomeric vehicles on complex road conditions, aerodynamic resistance and network communication lag and proposed an integrated platoon control framework. Han et al 25 designed a robust forecast controller with tamper-resistance function for the problems of time delay, disturbance, and parameter uncertainty faced by supercavitating vehicles. For linear discrete time-delay systems, Ghrab et al 26 considered the effects of uncertainties on state and delay state vectors and proposed a controller based on sliding-mode algorithm.…”

This article investigates the safety control problem of intelligent networked vehicle and utilizes the sliding-mode control to solve the system with time delay, system disturbance, and parameter uncertainty. First, the modeling of automobile system is introduced. What’s more, time delay, parameter uncertainty, disturbance, and attack are added to the original model. Then, designed an integral sliding-mode surface and given the sufficient conditions for system stability using linear matrix inequalities. Furthermore, the controller is designed according to the slide approach rate, and it is proved that the designed controller can make the system state reach the sliding surface in finite time. Finally, the simulation is used to verify the effectiveness of the arithmetic.

“…In addition, time delay and uncertainty exist in many practical systems such as control system and circuit system, and their existence affects the stability of the system (Gu et al, 2003;Hale and Lunel, 2013;Yang et al, 2021). Therefore, the study of time delay and uncertainty is meaningful and has received wide attention (Abolpour, 2021;Han et al, 2021;Khan and Nigar, 2021;Rahimi and Binazadeh, 2021;Yang, 2023;Zhou et al, 2021). Han et al (2021) studied the time delay and parameter uncertainty of the supercavitating vehicle and designed a robust controller.…”

Using the Hamiltonian function method with different powers, this paper studies the observer-based finite-time robust control problem of general nonlinear uncertain systems with time delay and presents some new results on this issue. First, by applying Hamiltonian realization method, the paper develops an equivalent Hamiltonian form of original system and designs its observer system. Then, based on the observer system, we study finite-time control problem and present several finite-time stabilization and finite-time robust stabilization results by using the augmented technology and the Lyapunov method. Finally, a real unmanned vehicle is used to verify the performance of the observer-based finite-time robust stabilization controller. Different from the existing literature on Hamiltonian method, the Hamiltonian function in the paper has different powers, which implies that the results developed in the paper have a wider range of application.
