英文摘要：

The characteristics of a PCI （peripheral component interconnect ） -based multi-axis real-time control system for realizing high-accuracy motion control were introduced. To reduce the workload from host computer and utilize the intelligence of DSP（ digital signal processor） efficiently for a complex task, the developed controller was designed with master-slave structure. The controller can also use serial communication control instead of PCI bus to satisfy users＇ requirements to some applications. The hardware development was focused on multi-axis controller, PCI local bus control logic, and PCI bus design; these parts are key technol- ogies for a PCI-based controller design. Through a test in which a 3-DOF manipulator was used to follow a spatial screw trajectory, it was proved that the developed multi-axis controller can realize a near-real-time high-accuracy coordinated motion control.
