Development of collaborative research initiatives to advance the aerospace sciences: Emphasis in power electronics

摘要

Single-chip microprocessors are widely used in the motion control industry. The single-chip implementation is economic and compact, but inflexible. This inflexibility restricts and engineer when quick laboratory implementation and testing of a new control scheme are desired. The need for a quick and flexible means to test new control methods has prompted the design of a general purpose DSP 56001 development system. With this system, new control algorithms can be quickly tested and evaluated. If satisfactory system performance is achieved, then a dedicated single-chip controller can be constructed. This methodology shortens the development time while increasing system reliability. At present, most DSP based implementation of motion control is based on the products of the TMS family. In this paper, a general purpose, flexible Motorola DSP56001 development system (DSP56KDS) for motion control is presented. The configuration and operating principles of the DSP56KDS are presented in the following sections, including the hardware and software organizations. A detailed discussion of peripheral board design, so critical for motion control, is included in the hardware description. The basic equations of the brushless DC (BLDC) machine follow. Finally, experimental results of a vector controlled BLDC machine with full digital implementation are given to illustrate the high performance characteristics of the DSP56KDS.
