摘要

Electric actuator dual-redundancy servo system consists of dual-redundancy rare earth permanent magnet (REPM) brushless DC machine (BLDCM), digital signal processor (DSP) and some periphery circuits, which implements actuator servo function. The same redundancy of power and torque can be obtained, current balance on dual-redundancy working state is investigated. It analyses several causes of current unbalance and possible consequences respectively. A method of current balance in a real system is given. The experiment result shows that the method is simply and practically. Both of the two redundancy currents are obviously consistent after adding current balance. The system performance is improved greatly.
