摘　　要：提出了一种带状态观测器的逆变器增广状态反馈控制和重复控制技术。在分析了单相逆变器的连续时间和离散时间模型之后,详细介绍了逆变器的增广状态反馈控制的原理和设计方法。为了减少检测装置和提高数字控制系统的性能,设计了基于电容电压和电容电流的状态观测器。最后简单介绍了逆变器的重复控制技术,并且设计了带状态观测器的逆变器增广状态反馈极点配置和重复控制复合控制系统。实验结果验证了应用该控制方法的逆变器能够得到良好的稳、动态性能。A novel inverter control system based on state-feedback integral control and repetitive control with state-observer is presented. The theory and design method of state-feedback integral control technique for inverter are introduced particularly after analyzing the continuous and discrete models of the single-phase inverter. A state-observer based on the voltage and current of the capacitance is designed for reducing measure equipments and improving the performances of the digital control system. At last, repetitive control technique for inverter is introduced simply, and the complex control system for inverter based on state-feedback integral control and repetitive control with state-observer is designed. Experimental results show that the inverter which is controlled by the complex system can achieve good steady and dynamic performances.
