  • ICIC (1) - Auto Position Control for Unmanned Underwater Vehicle Based on Double Sliding Mode Loops
    Intelligent Computing Theories and Application, 2018
    Co-Authors: Wei Jiang, Xiao-feng Kang, Liang Liang Wang
    Abstract:

    To deal with the large speed jump and Position overshoot when desired Position changes suddenly for UUV in the horizontal plane, an Auto Position controller based on double sliding mode loops is proposed. In comparison with the conventional control approach, the virtual speed is adopted in the proposed controller designing. Double loops are contained in the designed controller, and sliding mode surface is both contained in the outer loop and inner loop. The outer loop generates the virtual speed of UUV to avoid the large speed jump, while the inner loop realizes the speed tracking and eliminate the error between virtual speed and real speed. To estimate the uncertainty of the UUV’s motion model and the environment disturbance, an adaptive law is adopted. The stability of the proposed control method is proven based on Lyapunov stability theory, and the effectiveness of the proposed controller is demonstrated through simulation.

  • The Study of Active Noise Control Method for Moving Target in Noisy Space
    Applied Mechanics and Materials, 2011
    Co-Authors: Yan Jian Liao, Alan Peter Slade, Hong Yan Luo, Li Chen
    Abstract:

    For the noise problem of moving target in noisy space, This work is dedicated to developing a novel and promising solution based on the moving target tracking technology and the active noise control (ANC) technology. The development process began with the simplified sound field interaction model, the “Auto Position tracking near head space ANC” strategy has been proposed from the modelling study. Furthermore, the primary experimental system that consists of the acoustic Positioning and tracking subsystem for tracking the control point and the ANC subsystem for generating the anti-noise signal is presented, with the emphasis on the development of the improved TDC-FXLMS ANC algorithm. Finally, the performance of the Auto-Position tracking near head space ANC device is evaluated by carrying out the primary experiments on an experimental evaluation system.

  • The study of active noise control method for noisy surgery tools
    Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2011
    Co-Authors: Bin Liao, Yan Jian Liao, Hong Yan Luo
    Abstract:

    Noise problem is encountered in many types of surgery, especially in orthopaedic surgery, where the cutting tool and its actuation part such as motor always generates big noise. This work is dedicated to developing a novel and promising solution based on the active noise control (ANC) technology to solve the noise problem in an orthopaedic theatre. The development process began with building an engineering evaluation model (EEM) to analyze the specifics of sound interactions and sound field involved in the noise problem. This model can describe the acoustic problem in a straightforward way, help to design a good control system and furthermore to assess the result and to optimize the control structure. Then the "Auto Position tracking near head space ANC" strategy was proposed from the model study. Furthermore, the real sound field measurement experiment proved the possibility of proposed design.
