摘　　要：海洋电磁发射机在非理想状况工作时母线会产生冲击电压,严重时损坏开关管和滤波电容,为此提出一种混合控制策略。首先,基于dq坐标系的前馈解耦控制策略分析海洋电磁发射机可控源整流电路的动态性能,其次,通过理论证明负载扰动和无功电流iq≠0影响控制系统的动态性能,然后提出在dq电流解耦控制中引入瞬态直接电流思想的改进q轴混合控制方法,在dq电流解耦控制中引入负载电流前馈和无功电流iq≠0环节,改善了d轴电流id的响应速度,提高了控制系统的动态性能。最后,实验结果对比表明,混合控制方法在负载突变、直流侧电压给定值突变和船上柴油发电机电压跌落3种情况下,直流侧电压超调差最小,与最长调整时间相比减少了65%左右。Aiming at the problem that the operation of the marine electromagnetic transmitter will lead to the generation of inrush voltage at the busbar,which will damage the switching tubes and filtering capacitors in serious cases,a hybrid control strategy was proposed.First,the dynamic performance of the marine electromagnetic transmitter controlled source rectifier circuit was analyzed under the feedforward decoupling control strategy based on the dq coordinate system.Secondly,it was proved theoretically that load disturbance and reactive current i q≠0 affect the dynamic performance of the control system.Then an improved q-axis hybrid control method was proposed that introduces the idea of transient direct current into the feedforward decoupling control under the dq coordinate system,and a load current feedforward link was introduced into the feedforward decoupling control based on the dq rotating coordinate system.And the influence of reactive current i q≠0 on the response speed of d-axis current id was used to improve the dynamic performance of the control system.Finally,a comparison of the experimental results shows that the hybrid control method minimizes the overshooting difference of the dc-side voltage and reduces it by about 65%compared to the longest tuning time under three scenarios,namely,sudden load change,sudden change of dc-side voltage givens,and dips in the voltage of the on-board diesel generator.
