摘　　要：把分数阶次的PIλDμ控制器引进UPQC直流电压的控制中。利用PIλDμ控制器的工作原理及优点,分别在Matlab和EMTDC/PSCAD实现了PIλDμ控制器和UPQC的仿真,通过两者间的接口实现了PIλDμ对UPQC直流电压的控制。仿真结果证明了该控制器较传统PI控制具有响应速度快和控制结果更精确等明显优势。该控制器能更准确描述系统特性,扩展了系统可能的优化范围,从而为精确控制的实现提供更加广阔的优化空间。The fractional PI^λD^μ controller is introduced into the UPQC DC voltage control. With the principle and the advantage of the fractional PI^λD^μ controller, the PI^λD^μ controller and the UPQC are simulated separately. By using the software Matlab and EMTDC/PSCAD. The PI^λD^μ control of the DC voltage is actualized through the interface of the Matlab and EMTDC/PSCAD software. Simulation results show that the control of the PI^λD^μ controller has faster control response and more accurate control result than the traditional PI control. It enlarges the field of system optimization, and it provides the higher optimized space to the accurate control. The fractional PI^λD^μ controller can describe the control system more correctly. It expands the optimization field so the wider precise control space is given to the control system.
