基于单神经元PI控制的逆变器系统仿真

Simulation of inverter system based on single neuron PI

将一种根据误差的大小来调节比例系数K值的单神经元PI控制器引入到逆变器的控制回路中,可以实现在线调整参数,在一定程度上不依赖于系统的模型。仿真结果表明:与常规的PI控制器相比该控制器的输出超调量较小,有一定的自适应能力,可以提高逆变电源系统的动态性能。

This paper introduces one kind of single neuron PI controller that can adjust the scale factor K according to the error to the inverter control loop, it can adjust the parameters online and does not rely on the model of the system. The simulation results show that ： this controller has smaller overshoot and has some adaptive capability, it has also capacity to good dynamic respond.
