摘　　要：基于非线性系统的分段线性化原理将三相整流性负载分解成3种状态,简化逆变器带整流性负载的建模与设计。同时基于结合重复控制、电容电压微分反馈和双环控制器的策略,详细分析使用所提出三相整流性负载模型的三相逆变器工作特性及其控制器设计方法。针对系统非线性特点,分别使用二阶阻尼理论、相平面法和奈奎斯特图分析稳定性。最后,根据以上的分析在三相逆变器平台进行实验,验证三相逆变器带整流性负载的建模以及基于所提出模型控制器设计和稳定性判断方法的有效性。Based on the principle of piecewise linear, three-phase rectifier load is decomposed into three states, simplifying the modeling and design of inverter. With a scheme incorporating repetitive control, dual loop controller and capacitor voltage differential feedback, a detailed analysis of operating characteristics, controller design method is further presented. The steady-state and dynamic performance of the designed inverter system is analyzed by means of damping theory, phase-plane analysis method and Nyquist diagram. Experimental results are provided to demonstrate and the feasibility and validity of the proposed model and designed scheme and stability determination method.
