    Stable anti-lock braking system using output-feedback direct adaptive fuzzy neural control
    (2003-10-08) W.-Y. Wang; G.-M. Chen; C.-W. Tao
    In this paper, an output feedback direct adaptive fuzzy neural controller for an anti-lock braking system (ABS) is developed. It is assumed that only the system output and the wheel slip ratio, is available for measurement. The main control strategy is to force the wheel slip ratio tracking variant optimal slip ratios, which may vary with the environment and assumed to be known during the vehicle-stopping period. By using the strictly-positive-real (SPR) Lyapunov theory, the stability of the closed-loop system can be verified. To demonstrate the effectiveness of the proposed method, simulation results are illustrated.

    Robust sliding mode-like fuzzy logic control of anti-lock braking system
    (2003-03-14) W.-Y. Wang; K.-C. Hsu; G.-M. Chen
    在本篇論文中,為了控制防鎖死煞車系統,我們提出一個具強健特性的類滑動模式的模糊邏輯控制器,該控制器並擁有自行調整死區參數的功能。我們主要的控制策略在於迫使滑差追蹤並維持在最佳值0.2。考慮包含於汽車煞車系統中不確定因子的影響,本文所提出之控制器的表現仍具穩定性及可信賴性。我們並以防鎖死煞車系統模擬為例,來證明該控制器的正確性及有效性。

    Robust sliding mode-like fuzzy logic control for anti-lock braking systems with uncertainties and disturbances
    (2003-11-05) W.-Y. Wang; K.-C. Hsu; T.-T. Lee; G.-M. Chen
    In this paper, we propose a robust sliding mode-like fuzzy logic controller for an anti-lock brake system (ABS) with self-tuning of the dead-zone parameters. The main control strategy is to force the wheel slip ratio tracking the optimum value 0.2. The proposed controller for anti-lock braking systems provides a stable and reliable performance under the uncertainties in vehicle brake systems. Simulation results will show the validity and effectiveness of the proposed sliding mode-like fuzzy logic controller.

    On-line genetic fuzzy-neural sliding mode controller design
    (2005-10-12) P.-Z. Lin; W.-Y. Wang; T.-T. Lee; G.-M. Chen
    In this paper, a novel online B-spline membership function (BMF) fuzzy-neural sliding mode controller trained by an adaptive bound reduced-form genetic algorithm (ABRGA) is developed to guarantee robust stability and tracking performance for robot manipulators with uncertainties and external disturbances. The general sliding manifold is used to construct the sliding surface and reduce the chattering of the control signal, which can be nonlinear or time varying. For the purpose of identification, the proposed BMF fuzzy-neural network trained by the ABRGA approximates the regressor of the manipulator. An adaptive bound algorithm is used to aid and speed up the searching speed of the RGA. Simulation results show that the proposed on-line ABRGA-based BMF fuzzy-neural sliding mode controller is effective and yields superior tracking performance for robot manipulators.

    Fuzzy Control Using Intuitive Image Analysis
    (2008-05-27) G.-M. Chen; P.-Z. Lin; W.-Y. Wang; T.-T. Lee; C.-H. Wang
    In this paper, a novel fuzzy control scheme using intuitive image analysis is developed to imitate the intuitive human control behavior determined through human eyes. A CCD camera is used to gather the images of the controlled plant, and a simple algorithm is proposed to analyze the images. Unlike that in the visual servo control systems, the image information is utilized in a more intuitive way via the proposed image analysis algorithm. The difference between a reference image and the current image is numerically expressed and directly used by a fuzzy control system using a human-like control law. To investigate the effectiveness of the proposed fuzzy control scheme, it is applied to an inverted pendulum system. Simulation results show that the proposed scheme can achieve favorable tracking performance without prior knowledge of the controlled plant.

    Observer-Based Direct Adaptive Fuzzy-Neural Control for Anti-lock Braking Systems
    (中華民國模糊學會, 2006-12-01) G.-M. Chen; W.-Y. Wang; T.-T. Lee; C.-W. Tao
    In this paper, an observer-based direct adaptive fuzzy-neural controller (ODAFNC) for an anti-lock braking system (ABS) is developed under the constraint that only the system output, i.e., the wheel slip ratio, is measurable. The main control strategy is to force the wheel slip ratio to well track the optimal value, which may vary with the environment. The observer-based output feedback control law and update law for on-line tuning of the weighting factors of the direct adaptive fuzzy-neural controller are derived. By using the strictly-positive-real (SPR) Lyapunov theory, the stability of the closed-loop system can be guaranteed. Simulation results demonstrate the effectiveness of the proposed control scheme forABS control.

    Image-based fuzzy control system
    (Institution of Engineering and Technology, 2008-03-27) G.-M. Chen; P.-Z. Lin; W.-Y. Wang; T.-T. Lee; C.-H Wang
    A novel image-based fuzzy control (IBFC) scheme is developed to imitate the way humans use visual information to control objects. A CCD camera gathers images of the controlled plant, and a simple algorithm analyses the images. The proposed image analysis algorithm utilises image information more intuitively than visual servo control systems. The difference between a reference image and the current image is numerically expressed and directly used by a fuzzy control system using a human-like control law. To investigate the effectiveness of the proposed IBFC scheme, it is applied to control an inverted pendulum system. Simulation results show that the IBFC system can achieve favourable tracking performance without prior knowledge of the controlled plant.
