  • Robust Cross-Coupling Synchronous Control by Shaping Position Commands in Multiaxes System
    IEEE Transactions on Industrial Electronics, 2012
    Co-Authors: Chin Sheng Chen, Liyeh Chen
    Abstract:

    This paper proposes a new structure for cross-coupling synchronous controller using an H∞ control scheme to shape Position Commands for precise tracking in multiaxial motion control, together with its stability analysis. This proposed structure has the advantage that the controller has a simpler design process and more robust performance than conventional ones. The proposed controller is evaluated and compared simulated and experimentally with an unsynchronous controlled system and a conventional system. The simulated and experimental results show that the new structure reduces the Position synchronous error remarkably. In addition, this new controller can easily be implemented on most currently used motion systems used by reprogramming the reference Position Command subroutine.

  • cross coupling Position Command shaping control in a multi axis motion system
    Mechatronics, 2011
    Co-Authors: Chin Sheng Chen, Liyeh Chen
    Abstract:

    A new structure of a cross-coupling Position Command shaping controller (CPCSC) for precise tracking in multi-axis motion control is proposed in this paper. This controller feedforwards the cross-coupling terms, based on the geometrical relationship between the tracking and contouring errors, to compensate for the contouring error in real-time. Compared with the conventional multi-axis cross-coupling control (CCC) system, this new structure has the advantage that its compensators in CCC have a simpler design process than conventional ones, as does its stability analysis. The proposed controller is evaluated and compared experimentally with a traditional uncoupled and a conventional CCC controller on a multi-axis Positioning system controlled by microcomputer. The experimental results show that the new structure remarkably reduces contour error. In addition, this new controller can be implemented easily on most current systems by reprogramming the reference Position Command subroutine.

  • Position Command shaping control in a retrofitted milling machine
    International Journal of Machine Tools & Manufacture, 2006
    Co-Authors: Chin Sheng Chen, Stephen P. Tseng
    Abstract:

    A Position Command shaping controller, hybrid structure of feedforward controller and cross-coupling controller, for accurate contouring in motion control is proposed in this paper. The feedforward controller can improve tracking performance of single axis and the cross-coupling controller guarantees the reduction in contour error for multi-axis motion. When compared with the conventional motion system, this new structure has the advantage that the compensators have a simpler design process than conventional ones and so does its stability analysis. The proposed compensators (or controllers) are evaluated and compared experimentally with a traditional controller on a microcomputer controlled dual-axis Positioning system. The experimental results show that the new hybrid structure reduces remarkably the tracking error and contour error. In addition, this new controller can be implemented easily on a majority of motion systems in use today via reprogramming the reference Position Command subroutine.

  • LMI-based Position Command design of table systems considering compensation for impact force and interference
    2015 IEEE International Conference on Mechatronics (ICM), 2015
    Co-Authors: Naoto Sugiura, Makoto Iwasaki
    Abstract:

    This paper presents a Position Command design methodology for table drive systems utilizing for a contact operation. In high performance mechatronic systems utilizing for contact operations such as picking up and/or placing on materials, force control is strongly requested to prevent a damage of materials due to impact force. Moreover interference force from other axis deteriorates Position control performance. In this paper, the stability condition of the impact force and interference force are clarified, and the linear matrix inequality (LMI) design framework is applied to improve the control performance, where the Position Command of the system is theoretically designed under the constraints against the impact force and interference. The effectiveness of the proposed design has been verified by experiments using a prototype.

  • Position Command shaping for vibration suppression considering target Position correction
    Electrical Engineering in Japan (English translation of Denki Gakkai Ronbunshi), 2009
    Co-Authors: Masafumi Yamamoto, Kazuaki Ito, Makoto Iwasaki, Nobuyuki Matsui
    Abstract:

    This paper presents a Command shaping technique based on a minimum jerk control approach that takes into consideration target Position correction during motion, for the fast and precise Positioning in vibratory mechatronic systems. The Positioning controller is designed using a two-degree-of-freedom control: a feedback compensator is synthesized by H-infinity control design to ensure the robust stability, while a feedforward compensator suppresses the vibration in response based on a coprime factorization expression of the plant mechanism. The Command shaping, on the other hand, eliminates the corresponding vibration components of the primary and secondary models in the Position Command, where the continuity of jerk component in the Command can be ensured against the target Position correction. The effectiveness of the proposed shaping technique has been verified by experiments using a table drive system on a machine stand. (C) 2009 Wiley Periodicals, Inc.

  • LMI-based robust Command shaping against plant perturbations in fast and precise Positioning
    2009 ICCAS-SICE, 2009
    Co-Authors: Masafumi Yamamoto, Makoto Iwasaki, Nobuyuki Matsui
    Abstract:

    This paper presents a novel Position Command shaping approach for the mechanical vibration suppression in mechatronic systems. Although conventional Command shaping approaches can suppress the specified mechanical vibrations, mechanical and/or electrical perturbations in plant may deteriorate the motion performance. In this research, a linear matrix inequality (LMI) design framework is applied to eliminate the deterioration in Positioning, where a robust Command shaping against the plant perturbations can be directly achieved under the constraint of state variables in system. The effectiveness of the proposed shaping has been verified by numerical simulations and experiments using a prototype.

    Abstract:

    This paper presents a Command shaping technique based on a minimum jerk control approach for the fast and precise Positioning in vibratory mechatronic systems, considering a target Position correction during the Positioning motion. The Positioning controller is designed in the framework of 2-degrees-of-freedom control: a feedback compensator is synthesized by a H infin control design to ensure the robust stability, while a feedforward compensator suppresses resonant vibrations in response based on a coprime factorization expression of the plant mechanism. The Command shaping, on the other hand, eliminates the corresponding vibration components in the Position Command, where the continuity of jerk component in the correction profile can be ensured against the target Position correction. The effectiveness of the proposed shaping technique has been verified by experiments using a table drive system on machine stand.

  • Fast and precise Positioning of ball screw-driven table system using minimum jerk control-based Command shaping
    International Workshop on Advanced Motion Control, AMC, 2006
    Co-Authors: Kazuaki Ito, Makoto Iwasaki, Masafumi Yamamoto, Nobuyuki Matsui
    Abstract:

    This paper presents a minimum jerk transition method-based Position Command shaping without the specified frequency components. In the mechatronic fields, the 2-degrees-of-freedom Position controller is well-known powerful tool to realize both the robust stability and the fast and precise Positioning performance. On the other hand, the notch filter to suppress the lower frequency vibration deteriorates the Position responses due to the essential phase delay of the notch filter. From the standpoint of view of the frequency component in the Command waveform corresponding to the resonant frequency causes the resonant vibration, the Command shaping should be considered as one of design freedoms. In this paper, the minimum jerk control-based Position Command shaping is applied instead of the notch filter to suppress the lower frequency vibrations such as a machine stand vibration. The application of the Position Command shaping provides better vibration suppression performance and reduces the calculation cost/time for the signal processing. The effectiveness of the proposed Position Command shaping has been verified by experiments using a table drive system

  • GA-based autonomous design of robust fast and precise Positioning considering machine stand vibration suppression
    Second International Conference on Power Electronics Machines and Drives (PEMD 2004)., 2004
    Co-Authors: K. Itoh, Makoto Iwasaki, Nobuyuki Matsui
    Abstract:

    This paper presents a novel genetic algorithm (GA)-based autonomous compensator design and Position Command shaping considering the stand vibration suppression for the fast and precise Positioning of mechatronic systems. The Positioning system is mainly composed of a robust 2-degrees-of-freedom (2DOF) controller based on the coprime factorization description. The feedback compensator based on H/sub /spl infin//, design framework in the 2DOF controller ensures the robustness against the variations of resonant vibration mode. The feedforward compensator and Position Command, on the other hand, can be autonomously designed by the optimization capability of GA, in order to achieve the desired Positioning performance and to suppress the machine stand vibration. The effectiveness of the proposed optimal design has been verified by experiments using a table drive system with ball screw.
