A biomimetic controller with online adaptation of impedance and force is applied to a full kinematic and dynamic model of the Baxter bimanual robot. A set of fuzzy logic engines are proposed to infer the values of tuning gains which affect the control performance and control effort of the controller, which would conventionally be set to a static value based on expert knowledge of the controller; the aim of this being to avoid the use of arbitary values to set these values. A simulated experiment is carried out, where the Baxter robot is required to move an object through a trajectory while subjected to two different disturbance forces in four phases. The controller with fuzzy inferred control gains is compared against the same controller with fixed gains to gauge the effectiveness of the new method. Results show that fuzzy inference of control gains impart an improvement in both tracking error and control effort.

In the recent years haptic interfaces became a reliable solution in order to solve problems which arise when humans interact with the environment. If in the research area of the haptic interaction between human and environment there are important researches, a innovative approach for the interaction between the robot and the environment using haptic interfaces and virtual projection method is presented in this paper. In order to control this interaction we used the Virtual Projection Method where haptic control interfaces of impedance and admittance will be embedded. The obtained results, validated by simulations assure stability, stiffness, high maneuverability and adaptability for rescue walking robots in order to move in disaster, dangerous and hazardous areas.

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.

Jiqiren/Robot 2013年第1期35卷 52-59+66页

作者： Li, Dongjie Rong, Weibin Sun, Lining Xiao, Wanzhe Zou, Yu State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin 150001 China Institute of Electrical Control and Automation Technology Harbin University of Science and Technology Harbin 150080 China

In order to increase the interaction of nanomanipulation, a tele-nanomanipulation platform with virtual 3D visual feedback and virtual force sense feedback is built by combining with the virtual reality technology and the force feedback device. To ensure that the virtual environment is able to reflect the real nanomanipulation environment accurately, the collision detection and force sensing rendering of the virtual model is designed in detail. The virtual match link between the force feedback device and virtual environment is introduced to ensure the stability of the force interaction interface and to increase the coordination of the master control module. Aiming at the accurate nanomanipulation, the image characteristics extraction method based on the region of interest is adopted to exact the depth information of probe. Then the relationship of image fuzzy degree and the distance between the probe and the substrate is quickly established, and the closed-loop control of the probe is realized. Finally, with the developed platform and the proposed method, the shift experiments of single ZnO nanowire are completed.

The feedback of position and attitude information are important for the autonomous control of a quadrotor unmanned aerial vehicle (UAV). But in the GPS-denied environments, it is hard to obtain the quadrotor UAV's position. The pose estimation problem for a quadrotor UAV is addressed in this paper. A miniature laser range finder and a miniature attitude heading reference system (AHRS) unit are employed as the main onboard sensors. And a new pose estimation algorithm is developed to provide accurate estimation for the UAV's position and attitude which can be utilized for the flight controller in the GPS-denied environments. © 2013 TCCT, CAA.

This paper generalizes the concept of the depth-independent interaction matrix, developed for point and line features in our early work, to generalized image features. We derive the conditions under which the depth-independent interaction matrix can be linearly parameterized by the geometric parameters of the generalized image features, and propose an adaptive visual servo controller for robot manipulators using the generalized image features whose geometric parameters are unknown. To estimate the unknown parameters on-line, we propose new error functions that are linear to estimation errors of the parameters and an algorithm that minimizes the error functions using multiple images. The Lyapunov theory is used to prove asymptotic stability of the proposed controller based on the nonlinear dynamics of the manipulator. It is also shown that in addition to points and lines, other common image features like distances, angles, areas, and centroids all satisfy the conditions for the linear parameterization. Experiments have been conducted to validate the proposed control method. © 2013 Elsevier Ltd. All rights reserved.

Chinese control Conference (CCC)

作者： Fu Wang Bin Xian Guoping Huang Bo Zhao The Institute of Robotics and Autonomous System the Tianjin Key Laboratory of Process Measurement and Control School of Electrical Engineering and Automation Tianjin University 300072 China

In this paper, an autopilot system for the quadrotor unmanned aerial vehicle (UAV) is developed by utilizing a digital signal processor (DSP) as the on-board micro-control unit (MCU). The hardware setup and the software are also developed for the autonomous flight control of the UAV. The main design procedure includes the controller board design, brushless DC motor driver design, sensor data processing software design, and flight control algorithm design. The control algorithm is developed based on the inner loop and outer loop control method. Proportional Derivative (PD) controllers are proposed for the attitude dynamics (inner loop) and position dynamics (outer loop) respectively. Autonomous hovering control is achieved via the control of roll angle, pitch angle, yaw angle and altitude of the UAV. Experiments results are included to demonstrate the hovering control performance.
