Subsequently, by leveraging the maximum values of relevant variables or functions within these invariant sets, the requirement for iterative differentiation of the virtual control signals in the controller design is circumvented. Furthermore, by simplifying the structure of the controller design, the effects arising from output quantization are effectively handled.

A hierarchical control architecture combining kinematic decoupling with distributed cooperation decomposes the complex high-degree-of-freedom coupled system into parallel joint-space optimization processes, thereby reducing computational complexity. The multi-step historical input increment is introduced to compensate for the joint drive lag effect, while the online pseudo-gradient estimation with a reset mechanism is incorporated to improve the tracking robustness under time-varying delays. The proposed global unified parameter strategy verifies the algorithm’s adaptability to degree-of-freedom expansion and heterogeneous joints.

Comparative experiments under random delay conditions demonstrate that the proposed control scheme enhances tracking precision over traditional PID control methods, reducing the steady-state error and peak displacement.

Specifically, the algorithm employs a gradient-weighted sum of local image regions as a quality evaluation metric, and iteratively updates exposure parameters by computing the first-order derivative of this metric with respect to the exposure settings. Moreover, scene irradiance information is incorporated to determine an appropriate update step size. To further mitigate motion blur, we constrain the camera’s maximum shutter time based on feedback from the visual odometry system. the efficacy of the proposed approach is validated through experiments conducted in both HDR and fast-motion scenarios.

First, considering the relationships among variables collected by the wind turbine’s supervisory control and data acquisition system, an operational mechanism-based method is designed to identify the outliers, while a novel multiple imputation approach is proposed to fill in the missing values and rectify the detected outliers to guarantee good data quality. Then, based on fuzzy and rough set principles, rolling fuzzy information granulation is used to capture the wind power fluctuation and construct high-quality training labels. Subsequently, the graph attention network with dynamic attention and gated recurrent unit, and the stacked broad learning system are developed separately as wind power interval predictors.

Purely data-driven methods, while successful in perception tasks, often suffer from a “black box” nature when deployed in safety-critical environments, leading to insufficient generalization and potential hazards. Therefore, the paradigm of trustworthy decision-making and control guided by physical world information has emerged. It integrates physical laws, system dynamics, and environmental constraints into AI models, either as regularization terms in the loss function, embedded within the network architecture, or through hybrid models. It allows AI to simultaneously learn from data and consistently follow physical laws. This paper compares trustworthy computing guided by physical knowledge with traditional data-driven methods, focusing on two representative paradigms: Physics-Informed Neural Networks (PINNs) and Physics-Informed Reinforcement Learning (PIRL). We present their core concepts and integration mechanisms, embedding physical laws via loss regularization or network architecture, and incorporating physics into the learning or control process. This paper reveals the significant improvements of the trustworthy computing in interpretability, robustness, and safety, providing a new path from “black box” to “physically interpretability” transformation for safety-critical domains such as autonomous driving, robot collaboration, and industrial process control.
