| 摘 要： | 提出了一种基于单神经元的直流电压在线辨识方法.该方法根据逆变器的开关平均模型建立了直流电压辨识的参考模型和参数可调的单神经元,以直流电压作为单神经元的加权系数,通过学习算法不断调整加权系数,从而实现辨识值跟踪实际值.基于有功平衡理论直接对电网电流进行控制,因而无需检测负载电流和逆变器输出电流,有效地降低了有源滤波器的成...

| Abstract: | A method of online DC voltage identification based on single neuron is proposed,which,according to the DC voltage identification reference model based on switch average model,takes the DC voltage as the weights of single neural and adjusts them by learning algorithm to realize the identification values well tracking the actual values.As the supply current is directly controlled based on the energy balance theory,the detection of load current and inverter output current is not necessary,which effectively red... |
