In this paper, we propose a simple sliding guideway with a hydraulically operated brake unit, which can control sliding friction force on a feed drive system. The sliding friction force is controlled by the brake force command generated from velocity information of a table and/or a servomotor. Several damping control laws are implemented in the brake force control unit. Structural vibration of ballscrew drives can be successfully controlled by this actively controlled sliding guideway in experiments.
