并联脉宽调制整流器非线性L2增益环流抑制控制
Circulating-current nonlinear L2-gain attenuation control of parallel pulse width modulation rectifiers
摘要
Abstract
For the circulating-current restrain in parallel pulse width modulation(PWM)rectifiers caused by the uncer-tain model parameters and external disturbances,the new control method,composed by the optimal L2-gain current inner loop control and the zero sequence current outer loop control,is proposed.The optimal L2-gain current inner loop control not only can realize the minimum gain of the disturbance to the output,but also can achieve the power transfer between the parallel PWM rectifiers.The zero sequence current outer loop control can retrain the circulating-current caused by the uncertain parameters and the disturbances.The simulation results of the parallel PWM rectifiers shows that comparing with the traditional proportional-integral control method,the new two loop L2-gain control method can significantly re-duce circulating-current between the parallel PWM rectifiers and improve the power supply quality,which is important to improve the stability of the power system.关键词
