In this context, the ability to coordinate these elements safely will eventually reach human limits, thereby limiting the achievable complexity. To address these challenges, higher levels of autonomy are being developed, supporting safer, larger, and more cost-effective operations. This study introduces cooperative control algorithms specifically designed for Dynamic Positioned vessels. In this framework, DP vessels are conceptualized as “drone ships”, capable of maintaining their position and executing trajectory tracking tasks collaboratively. The proposed methodologies incorporate robust nonlinear techniques formulated as cooperative protocols, including Sliding Mode Control (SMC) and the Super Twisting Algorithm (STA), to address a multi-agent consensus problem. These approaches consider the impacts of geometric and dynamic nonlinearities, as well as environmental disturbances that influence DP systems.

A novel error-based high-gain feedback switch control algorithm is developed specifically for speed and distance control, utilizing solely speed and distance information without relying on models. The designed control method can achieve the prescribed performance speed control when the anterior train is remote and guarantee the safe distance when the anterior train is closed-by.

To address this issue, this paper proposes an uncertainty-aware key-domain-preserving stacked auto-encoder (UADP-SAE) model developed to capture the spatiotemporal distribution characteristics of dynamic operational changes in industrial systems. Based on this, an uncertainty quantification framework is designed to guide feature learning of the model by using uncertainty estimates. In addition, heteroscedastic uncertainty related to input noise is incorporated into the loss function, mitigating the adverse effects of high-uncertainty data on feature learning and enhancing the reliability of knowledge acquisition.

By separating static and dynamic friction modeling, and using particle swarm optimization (PSO) to tune parameters, the proposed models achieve RMSEs of 0.43 μm and 1.14 mm, respectively.

This enhances the learning effect and improves convergence speed. Experiments show a significant RMSE reduction from 18 μm to 0.83 μm (95.4 % improvement), and tracking errors are reduced by 51.1 % compared to PDILC under standard conditions and 48.9 % under additional load conditions.

The approach integrates domain-specific physical principles with black-box models, overcoming the limits of traditional linear or purely black-box methods. The description of this novel framework is supported by a theoretical study on the effect of non-uniform observations on the accuracy of parameter estimation. Specifically, we demonstrate the existence of upper bounds on the parametric error resulting from missing measurements and aggregated observations. Then, the effectiveness of the approach is demonstrated through two case studies. These include a practical application with missing samples, i.e., the identification of a continuous stirred-tank reactor using real data, and a simulated Lotka–Volterra system under aggregated observations.
