基于H∞的重复电压控制器设计及研究

Research and Design Voltage Controller Base on H∞ Repetitive

敏感性负荷需要较高的电能质量支持,通常利用整流-逆变单独供电的方式提供高质量的供给。将H∞理论和重复控制理论相结合,设计了逆变器的电压控制器,使负荷侧的谐波总畸变率保持在较低的比率,增强系统抗御扰动的能力,仿真验证了该设计能减小电压电流波形畸变。

Sensitivity of the load requires a higher power quality support,it is usual to use rectifier-inverter to provide high-quality.H∞ and repetitive control techniques are put together to design voltage controller of inverter,making the total harmonic distortion rate of the load at a lower rate and enhancing the capacity of the system to resist disturbance.Simulation shows that the design can reduce the voltage and current waveform distortion.
