采用智能控制器的混合型有源电力滤波系统

介绍了一种基于数字信号处理器(DSP)的智能型混合有源滤波系统，该系统针对电网电流的不确定性和非线性等特点，在传统的混合型有源电力滤波系统的基础上，引入了先进的自适应模糊控制器，从而最大限度地降低了电网电流的畸变率。通过对有源滤波器投入前后电网波形的比较可以看出，所提出的智能型混合有源滤波系统大大改善了传统滤波器的滤波效果，对负载产生的各次谐波均具有良好的滤波性能。

DEVELOPMENT OF HYBRID ACTIVE POWER FILTER USING INTELLIGENT CONTROLLER

A novel intelligent hybrid active power filter system based on DSP (digital signal processing) is developed. Because the electrical source current is uncertain and non linear, an adaptive fuzzy controller is introduced into the traditional active power filter system. This new system can reduce the current deviation of the electrical source to the greatest extent. The experimental results confirm that the system has better filtering effect compared with the traditional active filter and can get perfect filtering performance in many conditions.
