摘　　要：介绍了单神经元PID的控制原理,将其用于逆变器的闭环控制系统中,给出了系统硬件框图,通过Matlab仿真分析可得,该逆变器在工作的整个过程PF值基本能达到1,并网电流与并网电压基本同频同相,随着并网功率的增加,并网电流THD逐步减小,保证了并网电能的质量。Introduction was made to the control principle of single nerve cell PID. Single nerve cells were used in a closed-loop control system of inverter and the hardware block diagram of the system was given. Matlab simulation analysis shows that in the whole process, the power factor value of the inverter is basically close to one and the connected-in current has the same frequency and phase with the connected grid. The connected-in current THD reduces step by step with the connected-in power, to have ensured quality of connected-in electrical energy.
