MICROCOMPUTER CONTROL OF A CURRENT SOURCE DC-DC CONVERTER Academic Article uri icon

abstract

  • A microcomputer-based time optimal control algorithm for a current source dcdc converter is presented. The optimal control strategy for our system is shown to be bang-bang or maximum effort. The closed-loop bang-bang control was tested on a 22.4-kW energy transfer system. This system was the prototype of an inductor-converter bridge (ICB) at Argonne National Laboratory. The ICB is used for bidirectional (two-quadrant) energy transfer between two large superconducting coils. The system test setup and operation is presented in some detail. The test results of the control system are presented. The difference between the ideal and actual test results is analyzed in terms of, accuracy, noise effects, quantization error, and instrumentation dynamic response. The results of this analysis are used for a systematic component specification of a microcomputer based bang-bang control system to achieve a required accuracy.
