摘要
针对航空静止变流器带非线性负载造成的输出电压波形畸变问题,分析了采用重复控制技术的单相静止变流器控制模型和补偿器的数学表达形式。给出了控制器参数的频域设计方法。通过单相500VA/400Hz静止变流器的原理样机实验,其结果表明此分析设计方法是正确可行的。同时也验证了采用重复控制技术解决航空静止变流器带非线性负载时的输出波形畸变问题是行之有效的。从而为三相大功率航空静止变流器的研制打下了良好的基础。
The repetitive control approach is applied to the single-phase aviation static inverter （ASI） for solving the wave distortion of the output voltage caused by nonlinear loads. Based on this approach, the control model and the compensator of the ASI are analyzed and designed here. The design of control parameters in frequency domain is also presented here. Experiment results, which are obtained from a 500VA/400Hz prototype, show that the design method is feasible and the concept to use the repetitive control approach to improve the wave distortion of ASI with nonlinear loads is verified practically. The conclusions can be used for the references of three-phase power static inverter.
