Sliding mode tracking control for miniature unmanned helicopters

引用

Chinese Journal of Aeronautics 2015年第1期28卷 277-284页

作者： Xian Bin Guo Jianchuan Zhang Yao Zhao Bo The Institute of Robotics and Autonomous System Tianjin Key Laboratory of Process Measurement and ControlSchool of Electrical Engineering and Automation Tianjin University

A sliding mode control design for a miniature unmanned helicopter is presented. The control objective is to let the helicopter track some predefined velocity and yaw trajectories. A new sliding mode control design method is developed based on a linearized dynamic model. In order to facilitate the control design, the helicopter＇s dynamic model is divided into two subsystems,such as the longitudinal-lateral and the heading-heave subsystem. The proposed controller employs sliding mode control technique to compensate for the immeasurable flapping angles＇ dynamic effects and external disturbances. The global asymptotic stability（GAS） of the closed-loop system is proved by the Lyapunov based stability analysis. Numerical simulations demonstrate that the proposed controller can achieve superior tracking performance compared with the proportionalintegral-derivative（PID） and linear-quadratic regulator（LQR） cascaded controller in the presence of wind gust disturbances.

Nonlinear asymptotic attitude tracking control of an underactuated 3-degree-of-freedom helicopter using neural network feedforward term

引用

控制理论与应用（英文版） 2013年第3期11卷 428-435页

作者： Xiang LIU Bin XIAN Jianchuan GUO Bo ZHAO Chen DIAO Institute of Robotics and Autonomous System Tianjin Key Laboratory of Process Measurement and Control and School of Electrical Engineering and Automation Tianjin University

This paper proposes a new asymptotic attitude tracking controller for an underactuated 3-degree-of-freedom （DOF） laboratory helicopter system by using a nonlinear robust feedback and a neural network （NN） feedforward term. The nonlinear robust control law is developed through a modified inner-outer loop approach. The application of the NN-based feedforward is to compensate for the system uncertainties. The proposed control design strategy requires very limited knowledge of the system dynamic model, and achieves good robustness with respect to system parametric uncertainties. A Lyapunov-based stability analysis shows that the proposed algorithms can ensure asymptotic tracking of the helicopter＇s elevation and travel motion, while keeping the stability of the closed-loop system. Real-time experiment results demonstrate that the controller has achieved good tracking performance.

Ultrafine silicon carbide (SiC) powders have garnered increasing attention due to their vast potential for diverse applications. In this study, we developed a plasma-enhanced fluidized bed reactor to crack hexamethyldisilane (HMDS), thereby producing SiC/NC composites with diameters ranging from 10 to 20 nm. This method enables large-scale and sustainable production of SiC/NC composites. Concurrently, nitrogen doping was achieved by introducing ammonia during the plasma process, which increased material defects and thus enhanced electrical conductivity. Moreover, the abundant hydrogen atoms in ammonia modulated the product properties, as evidenced by reduced particle size, enhanced crystallinity, and decreased free-carbon content. The synthesized composites were applied as anodes in lithium-ion batteries, and their feasibility was confirmed through extensive testing. Notably, SiC-150 exhibited a discharge capacity of 413 mAh g-1 after 200 cycles at 0.1 A g-1 and maintained a high specific capacity of 780 mAh g-1 even after 800 cycles at 0.5 A g-1. © 2025, The Authors.

Temporal-spatial cross-correlation analysis of non-stationary wind speed time series plays a crucial role in wind field reconstruction as well as in wind pattern ***,the near-surface wind speed time series recorded at different locations are studied using the detrended fluctuation analysis(DFA),and the corresponding scaling exponents are larger than *** indicates that all these wind speed time series have non-stationary ***,concerning this special feature( i.e.,non-stationarity)of wind signals,a cross-correlation analysis method,namely detrended cross-correlation analysis(DCCA) coefficient,is employed to evaluate the temporal-spatial cross-correlations between non-stationary time series of different anemometer ***,experiments on ten wind speed data synchronously collected by the ten anemometers with equidistant arrangement illustrate that the method of DCCA cross-correlation coefficient can accurately analyze full-scale temporal-spatial cross-correlation between non-stationary time series and also can easily identify the seasonal component,while three traditional cross-correlation techniques(i.e.,Pearson coefficient,cross-correlation function,and DCCA method) cannot give us these information directly.

Adaptive Backstepping Tracking Control of a 6-DOF Unmanned Helicopter

IEEE/CAA Journal of Automatica Sinica 2015年第1期2卷 19-24页

This paper presents an adaptive backstepping control design for a class of unmanned helicopters with parametric uncertainties. The control objective is to let the helicopter track some pre-defined position and yaw trajectories. In order to facilitate the control design, we divide the helicopter's dynamic model into three subsystems. The proposed controller combines the backstepping method with online parameter update laws to achieve the control objective. The global asymptotical stability (GAS) of the closed-loop system is proved by a Lyapunov based stability analysis. Numerical simulations demonstrate that the controller can achieve good tracking performance in the presence of parametric uncertainties. © 2014 Chinese Association of automation.

Planning a trajectory for a mobile manipulator to complete a task challenges extremely as the robot has high degrees of freedom (DoF), especially in an unstructured environment. In recent years deep reinforcement learning (RL) achieves excellent performance in control fields, this paper applies the state-of-the-art deep RL algorithms to solve whole-body motion planning and control problem for mobile manipulator reaching in different environments. The method generalizes the problem from collision-free environment to those with static or dynamic obstacles by using transfer learning. The experiments are evaluated in different environments and the results verify the feasibility. © 2024 IEEE.

In this paper we present concept, prototype and first experimental results of a force/ torque-sensor based motion control and fall prevention system for an active walker mobility aid to support walking and the sit to stand transfer. For detection of the user intention and for characterization of possible fall situations a 6Dforce/ torque sensor is used in combination together with a real-time SIMULINK® signal pre-and postprocessing. To improve situation awareness of the signal processing, a mathematical model of the human body is used in the background. Finally we present first experimental results acquired with a passive type rollator using our lab test course. © Springer Science+Business Media Dordrecht 2014.
