摘要
重复控制(RC)策略与传统控制策略相比,能显著提高被控对象跟踪精度,并有效抑制外部干扰,被广泛应用于精密控制、新能源发电和电能质量控制等领域。然而,RC内模固有延时结构决定了其动态响应特性将逊色于传统控制策略。此处提出一种改进型快速RC策略,利用6k±1次RC内模,可有效减少控制延时并提高跟踪速度,提出一套基于该结构参数设计方法。最后通过谐波电流源(HCS)验证上述算法的可行性和有效性。
Repetitive control(RC) strategy is an effective method to improve tracking precision and suppressing external disturbances when compared with traditional control strategies.It’s wildly applied in high-precision control,new energy generation and power quality control,etc.However,the inherent delay structure of internal control of RC determines that its dynamic response characteristics will be inferior to traditional control strategies.An improved fast RC strategy with(6 k±1)-order RC structure is used,which can effectively reduce control delay and improve tracking speed.A set of parameter design methods based on new structure is proposed.Experiment of(6 k±1)-order RC is performed on harmonic current source(HCS),which shows the validity and advantages of the proposed new design method.
