A high-precision fuzzy control algorithm with self-regulating factor for trajectory tracking in virtual-axis polishing machine tool

In this paper, we present a new trace-tracking control algorithm, in which a self-regulation factor is adopted to realize real-time position control with high-precision fuzzy controller. The mover current is adjusted by given acceleration to implement real-time control and to enhance the characteristic of trajectory tracking in virtual-axis polishing machine. The experiment results demonstrate that high-precision real-time trajectory control of position, speed and acceleration in each link has attained and the static and dynamic characteristics of machine are enhanced.
