| 摘 要： | 在基于嵌入式重复控制和传统P控制的复合控制方案的基础上,加入积分控制,应用于110V50Hz UPS的逆变环节,加速了调节过程,改善了系统静态特性。文章详细分析了系统的结构、重要控制参数的整定,并在SABER软件环境下建立50Hz UPS电源的逆变闭环控制系统仿真模型。仿真实验结果表明:采用此控制方案在额定负载范围内输出特性良好,能获得稳定的50Hz正弦电压,是一种高性能、低成本的控制系统。

| Abstract: | On the basis of the conventional P control and the plug-in repetitive control method in the 110 V 50 Hz online UPS,the application of integral control accelerate the adjustive process, and improve the static characteristic.The control structure and the important parameters of the system were described.The emulation model of the 50 Hz UPS close loop invert control system was designed in SABER.The results show that the proposed control scheme can stabilize the output 50 Hz sine wave well,is a costeffective wave for UPS invert control system. |
