摘要
传统无差拍控制应用于单相逆变电源时,存在对系统参数变化敏感的问题。利用BP网络的任意非线性表达能力对无差拍控制参数进行离线辨识,以实现无差拍控制器的精确设计。在MATLAB环境下,对系统进行了仿真与建模。结果表明,利用该方法设计的无差拍控制正弦波逆变器系统稳定性好、输出电压波形畸变率低,具有一定的实用价值。
The parameter sensitivity generated when the traditional deadbeat control was used in single phase inverter. Using the expressing ability of arbitrary nonlinear of BP network to make off-line identification for deadbeat control parameter in order to realize the exact design of deadbeat controller. Based on MATLAB, the system circumstance was simulated and modeled, the experimental results proved that the proposed deadbeat control sin wave inverter presented good stability, low output vohage aberration rate and had practical value.
