The proposed approach integrates a high-order super-twisting observer with a smooth super-twisting sliding mode control law to achieve a precise and rapid tracking performance. A smooth super-twisting sliding mode control is designed to ensure fast convergence of the speed tracking errors. Nonetheless, the incomplete state information resulting from lumped disturbances induces chattering in the system. To address this issue, a high-order super-twisting observer is devised to estimate the lumped disturbance and provide feedback compensation, thereby augmenting the robustness of the system. This study examines closed-loop finite-time stability using the Lyapunov function theory. An extensive comparison of the experimental and simulation results of the proposed control design with those of the classical sliding mode and super-twisting sliding mode shows its superiority and effectiveness.

In this algorithm, an online trajectory interpolation method between adjacent cutter-contact (CC) points is first implemented to acquire the ideal trajectory information of the robotic end-effector within one control cycle.

Based on this, this paper proposes the concept of maximum data truncation rate, which quantitatively characterizes the bandwidth savings. A pinning truncated sampled-data controller associated with competition–cooperation interactions is designed, and a tractable error system is constructed using coordinate transformation techniques. Then, aiming at reducing coupling strength, a dual-interval-dependent Lyapunov function is designed according to the characteristics of the control scheme and the network structure. Combining Lyapunov theory with inequality techniques, two sufficient criteria are developed to ensure the bipartite synchronization of competition–cooperation neural networks. Based on these criteria, two algorithms are developed to determine the minimum allowable coupling strength and the maximum allowable data truncation rate, respectively. Two improvements over the previous Lyapunov functions are discussed: reducing the allowable coupling strength and increasing the allowable data truncation rate.

Leveraging the capabilities and suitability of invertible neural networks, we deploy an architecture equipped with conditional affine coupling layers to approximate this diffeomorphism. A pivotal feature is the integration of an attention mechanism within these layers, enhancing the capture of complex interactions across various layers. Additionally, we propose an alternative strategy, which employs an invertible decoding neural network in conjunction with a frozen decoder, to refine the diffeomorphism approximation further.
