摘要
分析了基于同步谐波旋转坐标系下的电流跟踪控制策略,研究基于PR控制器的静止坐标系下的电流控制方法。理想的PR控制器在谐振频率下增益为无穷大,可以实现谐振频率相同的正弦信号无静差控制。因此,在PI控制的基础上通过分析并联谐振控制器,实现对特定次谐波进行重点补偿。
This paper presents the current tracking control strategy based on harmonic synchronous rota-ting coordinate system.The method of current control based on PR controller was researched under the static coordinate system.The gain of ideal PR controller was infinite at the resonant frequency and could achieve no static error control at the same resonant frequency sinusoidal signal.The parallel resonant controller was analysed on the basis of PI control to realize the specific sub-harmonic compensation.
