摘要
基于单相PWM可逆整流器的状态空间平均模型及输出波形特点,提出了适用于建立系统控制模型的平均值分离法和半周期平均法。通过解析分析和线性化处理,推导出有关交流侧电流幅度和直流侧输出电压的传递函数模型和离散化控制模型,并进行了稳态理论分析。通过Matlab仿真和样机实验结果证实了理论分析的正确性及控制模型的可行性。
Both method of average value separated and method of half cycle averaging which are applicable to system control modeling of single phase PWM reversible rectifiers were proposed in accordance with their state space averaging model and characteristic of output waveforms.Both transfer function model and discrete control model as concerns the AC- side current amplitude and the DC-side output voltage were derived from theory analysis and linearization processing.Also some steady state quantitative relations were derived out.The validity of the control model and theory analyses is confirmed by both Matlab numerical simulations and sample experimental results.
