A field programmable gate array (FPGA)-based digital control and communication module (DCCM), designed to be the backbone for future space power management (PMAD) systems, is developed and implemented. In this paper, the hardware architecture and logic design of the module are addressed. A basic proportional-integral controller and an advanced linear active disturbance rejection controller are implemented on the FPGA for feasibility and performance tests. The logic implementation of the control algorithms is presented and the hardware test results are shown. The disturbance rejection ability of both control algorithms arc evaluated and compared. The communication implementation is discussed. Finally, a multi-converter with communication function testbed is shown to explore the potential benefits of the new control and communication module.
