Document type:Conference article (CA) Conference name:2011 International Conference on Advanced Design and Manufacturing Engineering, ADME 2011 Conference date:September 16, 2011 - September 18, 2011 Conference location:Guangzhou, China Conference code:86611 Sponsor:Guangdong University of Technology; Huazhong University of Science and Technology; Hong Kong University of Science and Technology; Hong Kong Polytechnic University; University of Nottingham Publisher:Trans Tech Publications, P.O. Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:Though computer technology has brought about virtual manufacturing to expedite design and analysis through simulation and visualization, machines remain essential, as ultimately products need to be made. This paper presents a new type of 5-axis parallel machine tool based on a 3 degrees of freedom parallel platform manipulator with base mounted prismatic actuators. This machine tool is different from the Stewart platform type parallel machine tool in that its feed motion in X-direction is realized by the worktable on which work-piece is fixed and the parallel manipulator sliding on the gantry structure of the machine tool is responsible for the translation along Y-direction instead of the movable platform of the manipulator. Due to this special architecture, the workspace in X-direction and Y-direction of the new machine tool is enlarged greatly. and its rigidity is higher because of the adaptation of gantry structure. This machine tool is controlled by a PC based NC system in simultaneous 5 axes control mode. © (2011) Trans Tech Publications.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:Confirming the position in space of the camera axis and it perpendicular to the target surface has important significance for simplifying the camera calibration in interior parameters. This article conducted a study on this issue. First, it establishes the relationship of the world coordinate system, the target coordinate system, the camera coordinate system and the image coordinate system. The necessary camera calibration in external parameters and internal parameters are confirmed. Second, the first target coordinate system is adjusted to the same position with the world coordinate system. The adjustment principle of the camera axis perpendicular to the target column end surface is proposed. Namely, whether the camera axis perpendicular to the first target column end surface or not is confirmed by the CCD image edge whether it's round or not. As the world coordinate system is based on coordinate measuring machines, so the world coordinate of the first target column end surface circle is obtained. Then the second target is placed in between the camera and the first target, and the second target coordinate system is adjusted to the same position with the world coordinate system, and it is adjusted to the same coordinate (except y direction) with the first target column end surface circle's coordinates. So the images of the first target and the second target column end surface circle in the CCD surely are circles. Third, the method to seek for the camera axis is put forward, namely if the circles of the first target and the second target column end surface circle in the CCD are not concentric, then it shows the optical axis and the joined axis of the first and second target face round are not concentric. By adjusting the CCD camera's position, until the circles of the first target and the second target column end surface circle in the CCD are concentric, such the camera axis can be represented by the joined axis of the first and second target end round. Simultaneously the target circle's center reflects the deviation on CCD coordinate between the optical center and the CCD center. Finally, the camera internal parameters are expressed by the related parameters. © (2011) Trans Tech Publications.

By introducing backstepping technique, and utilizing common control Lyapunov technique and Schur lemma, an improved switched control is developed. Compared with the existing literature, the proposed approach fully considers the virtual error term which is generated in backstepping design. The virtual error compensation term is adopted in controller. It is great convenient for stability analysis. By theoretical analysis, the closed-loop control system is shown to be globally uniformly asymptotically stable. Finally, simulation results are presented to illustrate the effectiveness of the proposed approach. © 2011 Chinese Assoc of Automation.

Fuzzy logic systems are employed to estimate the unknown continuous functions. The control scheme ensures that the closed-loop system is semi-globally uniformly ultimately bounded (SGUUB). The tracking error is proved to be bounded and ultimately converges to an adequately small compact set. The feasibility is investigated by a simulation example. © 2011 Chinese Assoc of Automati.
