压缩机控制装置、压缩机系统及压缩机控制方法
摘要：
该压缩机控制装置对压缩机的流量进行控制，该压缩机具有相对出口侧流路并列连接的多个叶轮和调整各叶轮的流量的流量调整部，该压缩机控制装置具备：检测出口侧流路的压力的压力检测部；检测各叶轮的流量的流量检测部；基于压力检测部的检测结果向流量调整部输出每个叶轮的流量调整指令来进行控制的控制部，控制部对作为流量的下限目标值而设定的设定点与各叶轮的流量进行比较，基于比较结果对其他叶轮的流量调整指令进行修正。
摘要（英）：

This compressor control device, which controls the flow volume of a compressor having multiple impellers connected in parallel with respect to an outlet-side flow path and flow volume adjustment units that adjust the flow volume of each impeller, is equipped with: a pressure detection unit that detects the pressure of the outlet-side flow path; flow volume detection units that detect the flow volume of each impeller; and a control unit that controls the flow volume adjustment units by outputting flow volume adjustment commands for the impellers to the flow volume adjustment units, on the basis of the detection result from the pressure detection unit. The control unit compares the flow volume of each impeller with a set point that has been set as a target lower limit value for the flow volume, and corrects the flow volume adjustment commands for the other impellers on the basis of the comparison results
