摘　　要：直流侧电压控制是有源电力滤波器(active power filter,APF)的关键技术之一。直流侧电压的大小直接影响有源电力滤波器的补偿性能。在环境复杂的工业现场,有很多原因将导致APF与电网的公共耦合点电压不稳定。当电网电压波动时,原先设定的直流侧电压有可能不能满足补偿性能。针对这一问题,在传统PI控制的基础上,设计了一种专家PI控制器来对直流侧电压给定进行控制并控制电压动态过程。DC side voltage control is one of the key technologies of active power filter. DC side voltage affects the compensation performance of active power filter. There are many reasons will lead to the point of common coupling between the active power filter and the power system voltage instability in the complex environment of the industrial site.When the grid voltage fluctuation, the DC side voltage of the original setting may not meet the compensation performance. This paper designs a kind of expert PI controller of DC side voltage given control and dynamic voltage control process to solve this problem.
