The article examines the development of a system for monitoring the volumetric supply of liquid in pumping units. The relevance of the research is due to the growing requirements for automation of control of pumping systems. The key element of the system is the observer, which allows evaluating the main parameters of the installation, such as the pump rotation speed and the moment of resistance. The electric drive of the pump uses an asynchronous motor with a squirrel-cage rotor, the rotation speed of which is controlled. The pressure in the discharge pipeline is created by a centrifugal pump. The observer is based on a model of an asynchronous motor in a fixed coordinate system, and the Luenberger observer is used to estimate the rotation speed and torque of the pump. To identify the volume flow, a centrifugal pump model is used, parameterized by a second-degree polynomial. The authors present simulation results showing the high accuracy of the developed observer, with an error of no more than 3% in steady state. The results demonstrate the effectiveness of the proposed approach for constructing a monitoring system for pumping units.
