However, the existing learning-based motion control strategies suffer from insufficient feature extraction, resulting in limited prediction accuracy. To address this problem, this paper proposes a robotic arm motion control strategy based on a cascaded feature-enhanced elastic-net broad learning system (CFE-EN-BLS), which improves the trajectory tracking accuracy of robotic arms. Firstly, a motion control strategy of the cascaded feature-enhanced broad learning system (CFE-BLS) is constructed to fully extract data features to improve joint position-tracking accuracy. Secondly, combined with elastic-net regression, a motion control strategy for the robotic arm based on CFE-EN-BLS is designed to reduce feature redundancy. Finally, the learning parameters of the proposed control strategy are constrained by incorporating Lyapunov theory to bolster the convergence of the control strategy. Simulation and experimental results show that the proposed control strategy can effectively extract data features and achieve high-precision trajectory tracking control of the robotic arm.

In this study, a scheduling method based on a modified generative adversarial network (GAN) is proposed. The state characteristics, which are represented by equal-length information granules, are extracted from the time series of the influenced variables that consisting of a scheduling scenario, and the experience-based scheduling rules are constructed to identify the appropriate scheduling moment. Then, a novel generation framework is built, in which the generator is established by employing multiple GANs to avoid the negative influence of different distribution features on a single discriminator. Finally, a scheduling solution for the corresponding moment is calculated by matching the generated scenarios with the actual one.

This is achieved by constraining the pointing errors to follow a novel predefined time prescribed performance function (PT-PPF), designed in advance to satisfy pointing requirements. The time-varying attitude constraints are enforced using a barrier Lyapunov function (BLF)-based control law, synthesized through the backstepping and dynamic surface control technique.
