    Output Feedback Adaptive Dynamic Surface Sliding-Mode Control for Quadrotor UAVs with Tracking Error Constraints.Guoqiang Zhu, Sen Wang, Lingfang Sun, Weichun Ge & Xiuyu Zhang - 2020 - Complexity 2020:1-23.
    In this paper, a fuzzy adaptive output feedback dynamic surface sliding-mode control scheme is presented for a class of quadrotor unmanned aerial vehicles. The framework of the controller design process is divided into two stages: the attitude control process and the position control process. The main features of this work are a nonlinear observer is employed to predict the motion velocities of the quadrotor UAV; therefore, only the position signals are needed for the position tracking controller design; by using the (...)

    Multi-Indices Quantification for Left Ventricle Via DenseNet and GRU-Based Encoder-Decoder with Attention.Zhi Liu, Yunhua Lu, Xiaochuan Zhang, Sen Wang, Shuo Li & Bo Chen - 2021 - Complexity 2021:1-9.
    More and more research on left ventricle quantification skips segmentation due to its requirement of large amounts of pixel-by-pixel labels. In this study, a framework is developed to directly quantify left ventricle multiple indices without the process of segmentation. At first, DenseNet is utilized to extract spatial features for each cardiac frame. Then, in order to take advantage of the time sequence information, the temporal feature for consecutive frames is encoded using gated recurrent unit. After that, the attention mechanism is (...)

    Single-Leg Structural Design and Foot Trajectory Planning for a Novel Bioinspired Quadruped Robot.Mingfang Chen, Qi Li, Sen Wang, Kaixiang Zhang, Hao Chen & Yongxia Zhang - 2021 - Complexity 2021:1-17.
    To meet the stability requirements for moving quadruped robots, it is important to design a rational structure for a single leg and plan the trajectory of the foot. First, a novel electrically driven leg mechanism for a quadruped robot is designed in this paper to reduce the inertia of the leg swing. Second, a modified foot trajectory based on a compound cycloid is proposed, which has swing-back and retraction motion and continuous velocity in the x-axis direction. Third, a Simulink platform (...)

    Analysis and Optimization of Interpolation Points for Quadruped Robots Joint Trajectory.Mingfang Chen, Kaixiang Zhang, Sen Wang, Fei Liu, Jinxin Liu & Yongxia Zhang - 2020 - Complexity 2020:1-17.
    Trajectory planning is the foundation of locomotion control for quadruped robots. This paper proposes a bionic foot-end trajectory which can adapt to many kinds of terrains and gaits based on the idea of trajectory planning combining Cartesian space with joint space. Trajectory points are picked for inverse kinematics solution, and then quintic polynomials are used to plan joint space trajectories. In order to ensure that the foot-end trajectory generated by the joint trajectory planning is closer to the original Cartesian trajectory, (...)
