“…With multi-platform support, Unity3D facilitates straightforward cross-platform development and deployment [27]. Moreover, Unity3D's robust physics engine and effects system enable the simulation of realistic physics and environmental effects, thereby augmenting the realism of virtual test scenarios and providing a more precise grasp of the test process for users [28]. Unity is used to construct a virtual marine environment, formulate the destroyer and USV formations, model the path of projectile movement, create a sea fog visibility weather model incorporating sea breeze and other disturbances, and simulate diverse weather conditions for damage effectiveness testing [29], [30].…”

Conventional evaluations of naval artillery's destructive prowess are dependent on resourceintensive sea trials, which are neither economically viable nor advantageous for the cultivation of combat intelligence. To circumvent these limitations, we propose a method rooted in virtual reality for assessing the destructive efficacy of naval artillery ammunition against unmanned maritime targets. Leveraging the Unity3D engine, we construct a high-fidelity virtual testing environment and design corresponding testing tasks. The offensive strategy is devised considering the naval artillery's damage radius and range, incorporating factors such as the warhead's velocity, and determining its launch angle and direction. Following this, the projectile's trajectory is computed employing the point mass motion equation, facilitating the simulation of the projectile's entire life cycle trajectory. A Monte Carlo based model has been developed for assessing the damage effectiveness of naval artillery ammunition against unmanned boats. This model enables quantitative calculation of ammunition usage under varied damage probabilities, addressing issues related to the complexity of the testing process, the limited number of tests, and the challenges in computing damage probabilities for target impacts of naval artillery ammunition. The findings corroborate the precision and stability of the virtual reality based assessment method for naval artillery ammunition damage effectiveness against unmanned surface vessels in combat simulations. This verification holds substantial importance for enhancing the computation accuracy of damage effectiveness associated with naval artillery ammunition.

“…The Miniaturized Inertial Stabilized Platform (MISP) presents extensive application in Unmanned Aerial Vehicles (UAVs) and Unmanned Surface Vehicles (USVs) to stabilize electro-optical devices for high-precision control of the Line of Sight (LOS) [1][2][3][4][5]. This technology is indispensable for performing complex tasks, such as visual-aided autonomous navigation [6][7][8][9][10] and target tracking in coast patrol [11,12]. Moreover, the joint USV-UAV operations [13][14][15][16] in marine environments characterized by complex and random disturbances, such as wave motion, turbulence, and environmental gusts, are also required urgently.…”

This paper investigates an anticipatory activation anti-windup approach based on Linear Active Disturbance Rejection Control (LADRC) to address the influences of accelerated saturation on the actuators in a Miniaturized Inertial Stabilized Platform (MISP) with extreme external disturbance. The proposed method aims to eliminate the high-frequency vibrations on the Line of Sight (LOS) of electro-optical devices during actuator saturation. To achieve this, the Linear Extended State Observer (LESO) is modified by adding saturation feedback to the total disturbance observed state variable, which is operated as an anticipatory activation anti-windup compensator. The stability of the proposed controller is discussed, and the gains are optimized by the Linear Matrix Inequality (LMI) constraints though quadratic programming and an H-infinite performance indicator. Additionally, as the multiple activated scheme for anti-windup, the effectiveness of immediate activation in dealing with accelerated saturation is compared and analyzed. These comparisons and verification are implemented through simulations, where the external disturbance is introduced using recorded attitude data from USV sailing. Finally, experiments are conducted on an MISP for a visual tracking system, demonstrating that the anticipatory activation mothed effectively suppresses high-frequency vibrations on the LOS during instances of accelerated saturation.
