基于模糊辨识的UPS逆变器无差拍控制策略的研究

介绍了UPS逆变器无差拍控制的基本原理，通过仿真和实验分析了控制系统的稳定性和参数灵敏性，提出了基于在线模糊辨识的无差拍控制策略。实验结果表明，这种控制方法在控制对象参数变动时仍然保持了系统稳定性和输出电压的无差拍特性，大大提高了传统无差拍控制逆变器系统的鲁棒性。

Research on Deadbeat Control Strategy with Fuzzy Identification for UPS Inverters

The basic theory of the deadbeat control strategy is intoduced for UPS inverters, the stability and parameter sensitivity of deadbeat control system is analyzed, then a deadbeat control strategy is proposed based on on-line fuzzy system identification. Experimental results prove that this control strategy keep the characteristics of deadbeat and stability with change of the circuit, so the robustness of the system may be increased.
