Abstract

The objective of this paper is to demonstrate how digital signal processor (DSP) technology can be applied to servo motor control in order to generate closed-position-loop servo drives that can be applied in advanced manufacturing technology applications such as robotics, CNC and other machine positioning systems. Neither the DSP nor intelligent servo controls are new technologies in their own right. However, it is the combination of the two which has been innovatively applied at the Swinburne University of Technology (Hawthorn, Victoria, Australia) in order to generate a system which has considerable potential in terms of redesigning computer controlled production equipment through a distributed control architecture. The resulting technology has been entitled CIM-Drive and has been commercialised by the Softronics company in Australia. The critical factor in designing an intelligent servo system is the provision of a real-time focal area network that can be used for infer-servo communication and for supervisory control. A relatively simple networking scheme (entitled 'Softnet') was developed during the course of the research and is documented herein. A number of newer, commercially available alternatives such as the CAN-Bus, Field-Bus and LON bus are also highlighted in this paper to show the current development path being pursued at the CIM Centre.
