Abstract: Aiming at the problems of the current inbalance between two or multiple SRG(stitched reluctance generator),the systematic model of SRG and current sharing control was researched.After the analysis of the SRG mathematical model and the comparison of some common methods, the maximal current sharing method was proposed to be aoolied to the SRG current sharing control system.The nonlinear model of SRG was established by the interpolation lookup table method based on the twodimensional table of current、angle and flux from ansoft, the accuracy of the model was verified by the simulation result. A flow equalize cycle was added to the two SRG systematic model, the closedloop simulation was tested. The experimental results show that the systematic model can achieve averagecurrent by using maximal current sharing control while two generator had certain speed difference,proving the correctness and validity of the control strategy.
