摘　　要：针对统一电能质量调节器(unified power quality conditioner,UPQC)线性控制算法中存在的控制结构复杂、控制器参数整定困难以及控制延时等问题,提出一种基于有限集模型预测控制(finite control set model predictive control,FCS-MPC)的UPQC预测直接控制策略。在分析UPQC直接控制系统构成基础上,基于FCS-MPC基本原理,实现了同步旋转坐标系下UPQC的有限集模型预测直接控制系统建模,有效简化了控制器结构,降低了控制算法的复杂度;基于UPQC系统有功功率平衡以及负载基波电压幅值恒定原控制器参数整定困难以及控制延时等问题,提出一种基于有则,建立了适用于UPQC串联侧与并联侧预测直接控制策略的给定值产生机制;最后,采用Matlab/Simulink仿真软件将所提控制策略与传统线性控制算法进行了对比仿真,并基于DSP (digital signal processor)(10)FPGA (field programmable gate array)(10)TYPHOON HIL402实验平台进行了实验验证,仿真与实验结果验证了所提控制策略的有效性和可行性。Aiming at the problems of the complex control structure,the difficult parameter tuning and the control delay in the linear control algorithm of the unified power quality conditioner(UPQC),a direct predictive control strategy for the UPQC based on the finite control set model predictive control(FCS-MPC) is proposed.On the basis of the composition of the UPQC direct control strategy system analysis,and based on the basic principle of the FCS-MPC,the finite set model predictive direct control system modeling of the UPQC in the synchronous rotating coordinate system is realized,which effectively simplifies the controller structure and reduces the complexity of the control algorithm.Based on the basic mechanism of the direct control strategy and the characteristics of the finite set model predictive current control,a given value generation mechanism suitable for the UPQC predictive direct control strategy is given.Finally,the proposed method in this paper is controlled by the MATLAB/SIMULINK simulation software.The strategy is compared with the traditional linear control algorithm,and the experimental verification is carried out based on the DSP(10)FPGA(10)TYPHOON HIL402experimental platform.The simulation and experimental results verify the effectiveness and feasibility of the proposed control strategy.
