Integrated tuning of bi-axial servomechanisms for precise motion control

초록

In order to ensure high-speed and high-precision specifications in servomechanisms, tracking and contour errors should be minimized through optimal selection of servo parameters. In this paper, integrated tuning procedure based on the integrated design concept is performed to derive the optimal tuning method. Control parameters are optimally selected through a nonlinear constrained optimization problem of the integrated design process, while parameters of the mechanical subsystem are specified according to the identified mechanical subsystem model. Experimental results show that both tracking and contouring errors are significantly reduced by applying the proposed integrated tuning method.
