摘要:
针对有源电力滤波器的被控电流为周期变化的正弦量,提出引入重复控制对有源电力滤波器电流进行控制,以减小系统的稳态误差。通过检测电网电压和直流电压直接获得期望的电网电流,而无需检测负载电流和滤波电流,简化了检测电路。并且利用串级控制的思想,对电压环的参数进行设计,为有源滤波器控制器参数设计提供理论指导。该算法的复杂度小、实时性强和容易工程实现。实验结果表明,采用重复控制的有源滤波器使电网电流总畸变率从61.8%降至5.6%,功率因数从0.77提高到0.98。
Abstract:
Because the dynamics of filter current are much faster than DC voltage,cascade control can be designed with a voltage loop outside an inner current loop.The current loop controller based on repetitive control is introduced to eliminate the steady state error caused by the reference sinusoidal current.The expected supply current is directly calculated by the supply voltage and the output of the voltage loop controller.As a result,the detection algorithm is simplified.Discussions on the design of the voltage ...
