Dynamic Stiffness Analysis of Repetitive Control System ()
ABSTRACT
For dynamic stiffness enhancement, this paper
presents a new method for synthesizing repetitive controllers capable of
rejecting periodic vibration disturbance. Dynamic stiffness of the control
system is analyzed. Direct and quadrature dynamic stiffness are defined for the
repetitive controllers’ design. A trade-off method between the determinations
of the controller’s parameters is necessary such that both the rejecting
performance and stability can be achieved simultaneously. An illustrated
example of a twin linear drive system is given to verify the performance of the
proposed control design. The control performance of the present method is
evaluated in the experimental disturbance rejecting control system, where the
real-time control algorithms are implemented using a floating-point digital
signal processor. Both computer simulation and experimental results are
presented to illustrate the effectiveness of the proposed repetitive controller
design.
