摘要
为提高正弦逆变电源的波形质量和动态响应,在正弦逆变控制中引入模糊自适应PID控制技术。将逆变电源视作一个参考正弦信号的随动系统,建立了单相正弦逆变电源输出滤波单元数学模型,设计了模糊自适应PID控制器。利用Matlab/simulink仿真软件进行了仿真研究,结果表明,正弦逆变器逆变输出稳定、波形畸变小、对非线性负载有较好的适应性。
To improve the sine inverter power output voltage waveform quality and its system steady-state and dynamic performance,a sine inverter control design based on self-adaptive of fuzzy PID control was presented.The inverter system was seen as a standard sine wave servo system in the arithmetic. The mathematical model of inverter output waveform was built and self-adaptive fuzzy PID control system was designed. The simulation results in Simulink environment with a particular case show that the sine inverter has stable output, low voltage distortion and strong load disturbing resistance.
