摘　　要：为更有效地解决并联变流器结构所导致的环流问题以及不均流问题,在采用基于线性自抗扰控制(linear active disturbance rejection control, LADRC)的环流控制器基础上,结合蚁群算法与单神经元电压环,设计了一种新型的电压环结构。先结合神经元网络算法和比例积分(proportional integral, PI)控制理论的特点,设计出可实时整定参数的单神经元电压环结构,再考虑蚁群算法具有优化参数的特点,综合考虑设计出这种新型的电压环结构。最后对并联的变流器结构进行仿真分析,通过和传统的电压环进行比较,对比结果说明了在新型电压环的作用下,环流得到很好的抑制,不均流问题也得以解决,这就验证了所设计的新型电压环的有效性。In order to solve the problem of circulating current and non-uniform current caused by parallel converter structure more effectively,a new voltage loop structure is designed by using the circulating current controller based on linear active disturbance rejection control(LADRC),combining ant colony algorithm and single neuron voltage loop.Based on the characteristics of neuron network algorithm and(proportional integral,PI)control theory,a single neuron voltage loop structure with real-time parameter setting is designed.Then,considering the characteristics of ant colony algorithm with optimized parameters,this new voltage loop structure is designed.Finally,the parallel converter structure is simulated and analyzed,and compared with the traditional voltage loop,the comparison results show that under the effect of the new voltage loop,the circulating current is well suppressed and the uneven current problem is also solved,which verifies the effectiveness of the new voltage loop.
