本文对三相系统功率因数校正降阶滑模控制器(ROSMC)进行了分析和设计。尝试了一种用于选择滑动面系数以实现ROSMC的新的、系统的技术。前端是一个三相二极管整流器，后面是DC-DC Cuk转换器模块，具有公共的DC输出。参考电流的产生采用瞬时对称分量理论。该控制策略采用三个内环ROSMC电流控制器进行电源电流整形，外环电压环采用比例积分控制器进行负载电压调节。该方法控制策略简单，暂态响应快，功率因数接近1。为了验证所提方法的有效性，搭建了一个由dSPACE 1104信号处理器控制的样机。仿真和实验结果表明，该系统能在较宽的负载变化范围内提供稳定的输出电压，功率因数接近1。
In this study, the analysis and design of reduced-order sliding-mode controller (ROSMC) for power factor correction (PFC) in a three-phase system is presented. A new and systematic technique for the selection of sliding surface co-efficients to implement ROSMC is attempted. The front end is a three-phase diode rectifier followed by DC–DC Cuk converter modules with the common DC output. Instantaneous symmetrical component theory is used for reference current generation. The control strategy uses three inner ROSMC current controllers for source current shaping and an outer voltage loop using proportional integral controller for load voltage regulation. The proposed method offers simple control strategy, fast transient response and power factor close to unity. To validate the proposed method, a prototype controlled by dSPACE 1104 signal processor is set up. Simulation and experimental results indicate that the proposed system offers regulated output voltage for wide load variations and power factor close to unity.
