大功率直流发电机高精度恒流调节系统研究

High precision adjustment of DC generator lower output current

对某消磁船大功率直流发电机恒流调节系统进行了设计 ,考虑磁滞等因素的影响 ,建立了发电机及控制系统数学模型 ,利用Matlab/Simulink软件进行了仿真设计 ,并将SIMOREG 6RA70装置成功应用于该系统中 。

In order to apply the theory considering high precision adjustment under the case of DC generator exporting lower current, this paper proposes a design method of control system, constructs a hysteresis model of DC generator, and uses SIMOREG 6RA70 master in excitation controller. Finally, the simulation results are given and shown to be effective in practice.
