    We used to crank connecting shaft neck in the center of the neck as the origin of work piece coordinate system. Through the offset of the work piece coordinate, we made use of the method of the coordinate value in keeping with the real coordinate diameter or the relative location value of the work piece center. We designed a kind of crankshaft NC dresser which consists of the Siemens servo semi-closed loop control system, imported servo motor drive and double axle linkage. In the process of machining, by coordinate origin migration to solve the change of coordinate for grinding wheel off after grinding wheel and decreased diameter. It realized the constant speed grinding wheel through the numerical control programming and NC grinding parameter Settings to realize the rotating speed of infinitely variable speed. Practice proves that the NC dresser simplifies the NC programming of the wheel molding, avoids the complex digital control and computational analysis software, and prevents the interference of dressing tools and grinding wheels.

    Discrete-time prototype repetitive controllers considering pole-assignment and its application

    Zaier, R. ; Yamada, M. ; Funahashi, Y.
    SICE '98. Proceedings of the 37th SICE Annual Conference. International Session Papers

    A repetitive control system is proposed from the viewpoint of pole-placement. The contributions are as follows. Firstly, the proposed repetitive controller can assign all poles of the closed loop system on a disk with a given radius whose center is the origin. As a result, faster convergence of the controlled error to zero than the previous ones is obtained. Secondly, the proposed controller is obtained explicitly with no equation to solve. The design effort is independent of the period of the repetitive signals to be tracked or rejected, in other words, the design effort is very small even if the period is very large. Thirdly, the robustness of the control system is improved by introducing a low pass FIR filter in the controller. Finally, the proposed scheme is applied to DC servo motor system and the effectiveness is demonstrated by both simulations and experiments View full abstract»

    In this paper, a new approach to regulate any periodic signals with multiple periods is proposed and a useful discrete-time controller called multiple repetitive controller is presented. The contributions are as follows. First, the proposed multiple repetitive controller not only can be implemented with much less memory elements than the previous ones but also can provide much faster convergence of the controlled error to zero. Secondly, the proposed repetitive controller not only can assure the stability of the closed loop system but also can assign all poles of the system on a disk with a given radius whose center is the origin. Thirdly, the proposed controller is obtained in an explicit form and the design method requires to solve no equation. The design effort is very small even if the periods are very large. Finally, the proposed scheme is applied to DC servo motor system, and the effectiveness is demonstrated by simulation. View full abstract»

    Design of motion control systems via H-partial state feedback

    Miyamoto, S. ; Arinaga, S.
    Control Applications, 1994., Proceedings of the Third IEEE Conference on

    DOI: 10.1109/CCA.1994.381440

    IEEE Conference Publications

    This paper presents a design of motion control systems via H-partial state feedback. There are some difficulties such as limitation of the plant poles at the origin or pole/zero cancellations in the design of motion control with the H-mixed sensitivity problem. These difficulties can be solved by using partial state feedback control when the plant internal states are available. Partial state feedback control, which uses measurable states besides outputs, has the advantage that the number of pole/zero cancellations can be reduced View full abstract»
