摘要
基于单相逆变电源的数学模型,设计了一种能保证系统渐进稳定的控制方案.方案根据李氏稳定理论进行设计,并利用观测器观测控制律中的状态变量,同时采用滤波器对原始参考输出信号进行处理,用以产生控制律所需的连续光滑的输出信号及其微分量,设计保证了系统的稳定性及输出电压跟踪误差的收敛性.理论分析及实验结果均验证了控制方法的有效性.
Based on the model of single-phase voltage source inverters, the paper proposed a control method which could guarantee system stability. According to the Lyapunov stability theory, a state observer was used to estimate the variables adopted in the control law. Meanwhile, a 3^rd order filter was used to deal with the original output reference voltage so that smooth and continuous output reference voltages as well as its differential coefficient were generated. The method guarantees system stability and convergence of the output voltage tracking error. Theoretical analysis and experimental results verify the correctness of the method.
