Abstract
This paper presents a method to improve the accuracy of synchronous control systems for dual linear stages driven by linear servomotors in order to quickly eliminate the velocity and position synchronous errors of the dual linear stages. Two velocity controllers and a synchronous controller are designed for the control system. To decrease the velocity tracking errors, two velocity controllers are designed to follow the velocity tracking commands which are also the desired velocity profiles specified by the given tasks and have optimized acceleration and deceleration characteristics. Moreover, the synchronous controller is designed to quickly and stably eliminate the position and velocity synchronous errors of the two dual linear stages by improving the damping characteristics of the synchronous control system. The experimental results are presented to demonstrate the effectiveness of the proposed synchronous control system.
