CONTROL SYSTEM FOR A FLUID MANAGEMENT SYSTEM

Disclosed is a control system for a fluid management system. The control system includes: a controller configured to: access an estimated torque and estimated speed of a motor mechanically coupled to an impeller of a centrifugal machine; access at least one set of pre-determined performance data values associated with a known speed of the impeller, where each set of pre-determined performance data values includes: a plurality of flowrate values and a plurality of performance metric values; determine an operating point of the centrifugal machine based on the estimated torque, the estimated speed, and the at least one set of pre-determined performance data values; compare the determined operating point to a best efficiency point (BEP) associated with the centrifugal machine; and determine whether to change the speed of the motor based on the comparison. 本发明题为"用于流体管理系统的控制系统"。本发明提供了一种控制系统，该控制系统包括：控制器，该控制器被配置为：访问机械地联接到离心机的叶轮的马达的估计扭矩和估计速度；访问与该叶轮的已知速度相关联的至少一组预先确定的性能数据值，其中每组预先确定的性能数据值包括：多个流量值和多个性能度量值；基于该估计扭矩、该估计速度和该至
