摘要
针对传统调节器跟踪交流信号存在幅值和相位误差的问题,提出了具有良好交流跟踪和调控特性的PR调节器.首先通过理论分析得出了PR调节器的传递函数,并以数字化形式应用于单相SPWM逆变器系统.仿真和实验结果表明,该逆变器系统能实现对交流参考的无静差跟踪,且具有良好的波形输出质量。
Aimed at the errors of amplitude and phase occurred during the conventional regulator tracking the AC signals, a PR regulator that has a good performance of AC tracking and controlling was proposed. A transfer function of the PR regulator was obtained with theoretical analysis, and applied to the single-phase SPWM inverters digitally. The simulation and experiment results show that the tracking with zero steady-state errors for AC reference and a favorable output waveform can be realized by using the proposed inverter system.
