Summary: This paper presents an effective control method for three-dimensional overhead cranes with six degrees of freedom. It introduces a novel 3D-6DOF crane model that considers axial cargo oscillation. The hierarchical sliding mode control method is used to design the controller, and a radial basis function neural network is employed to accurately approximate the system's unknown dynamic model. Simulation results on Matlab software demonstrate the effectiveness of the proposed approach in reducing swing, oscillation, and achieving precise positioning.

Summary: This note points out some drawbacks in the Lyapunov function-based analyses for designing a backstepping sliding mode controller in the above-titled article, including ignoring terms in simplification of the time-derivative of Lyapunov functions and the inability to conclude the finite-time convergence of error signals from a Lyapunov function-based inequality.

Summary: In this paper, two state feedback strategies are proposed to exponentially stabilize eigenstates for quantum spin-1/2 systems. The state feedback is improved to increase the real-time state convergence rate and achieve exponential convergence. Global exponential stabilization is achieved with the help of noise-assisted feedback. The state convergence rates of all state feedback strategies are compared, and the superiority of the improved feedback control is verified in numerical simulations.

Summary: This paper presents the double chain-integrator finite-time convergence in a closed loop with a second-order bang-bang sliding control. The direct Lyapunov method carried out the stability analysis and the reaching time estimation using a suitable non-smooth strong Lyapunov function. Numerical comparisons were performed to assess the proposed strategy's effectiveness.

Summary: This paper proposes a novel positioning and anti-swing controller based on fuzzy sliding mode for an overhead crane. The trolley displacement and load swing angle are integrated into the same sliding mode surface to deal with the underactuated characteristics of the overhead crane. The introduced fuzzy rules adjust the control quantity to ensure the system state remains on this surface, improving the control system's robustness to parameter changes and external disturbances.

Summary: This paper proposes a rapid switching control scheme for stochastic qubit systems under measurement feedback, aiming to reduce the switching times between the two subsets of the state space and improve the control efficiency. The scheme successfully prepares specific states for single-qubit and multiqubit systems. It utilizes approximate bang-bang control laws in subset S-1 to speed up the control process, and control laws in subset S-2 to ensure the descent of the corresponding Lyapunov function and reduce the switching times.

Summary: In this paper, a novel variable structure controller is designed based on the nonlinear dynamic modeling of the crane. The nonlinear system is divided into two subsystems containing displacement and swing angle information, and overall sliding mode design is carried out to achieve ideal coupling control performance. A fuzzy controller is designed to improve the positioning accuracy of the system and strict stability analysis is conducted. The simulation and experimental results verify the superiority and effectiveness of the proposed method.

Summary: In this paper, a heterogeneous swarm control method based on a two-layer communication topology is proposed. This method addresses the challenges of controller design and computational complexity in large-scale heterogeneous swarm control. The method divides the swarm into independent sub-swarms and designs corresponding sub-swarm controllers to simplify the controller design. A two-layer communication topology is introduced to establish connections between each sub-swarm and the global leader, reducing the computational complexity. The controllers in the two-layer communication topologies are designed using sliding mode and dynamic surface methods, with stability proven using a Lyapunov function. Simulation results confirm the effectiveness of the controllers.

The fuzzy technique is employed to linearize the system and a fuzzy model with appropriate membership functions is established. The sliding mode control method is utilized to stabilize the system and handle external disturbances.

Summary: In this paper, a novel asymmetric barrier Lyapunov function is constructed using a translation transformation to achieve stability and security in the presence of interference. This is the first continuously differentiable barrier Lyapunov function (BLF) of this type. An adaptive sliding mode control (SMC) method based on the asymmetrical BLF is proposed, which can handle uncertain external disturbances and ensure safe navigation with bounded tracking error. The fixed-time convergence of the method is proved by the Lyapunov theory. The results show that it has stronger anti-interference ability, better robustness, and concise form in bad sea conditions.

Summary: This article addresses the dynamic sliding mode control problem for unmatched nonlinear parameter-varying systems. By constructing a linear sliding surface function and deriving the synthesis procedure of the sliding manifold based on a parameter-dependent Lyapunov function, the asymptotic stability of the system is guaranteed. Furthermore, a dynamic SMC law is proposed to guide the closed-loop system towards the sliding manifold in finite time, with both the sliding surface and control law depending on time-varying and measurable parameters. Simulation studies are provided to demonstrate the validity of the proposed method.

Summary: Most indoor environments are equipped with wheelchair adaptations or ramps, allowing mobile robots to navigate sloped areas without steps. These multi-level indoor areas present a challenge for robot navigation due to the sudden change in reference sensors. Using two robots (leader and follower) for rapid exploration and higher redundancy is proposed, with the leader robot using 3D LIDAR for mapping and a Kinect camera for RGB image acquisition.
