“…The simulated model was experimentally validated, finding differences in steady state from 7 to 14%. Gevorkov et al [12] carried out a mixed simulation and experimentation study of a flow control system with a variable speed centrifugal pump, using a flow sensor for feedback and a PI controller. The inaccuracy of the proposed model varied between 0.3 and 4%.…”

Flow rate and pressure are variables of great interest in the process control industry, especially in pumping systems. With the help of modeling and simulation, it is possible to understand the operation of these systems prior to their construction, in addition to allowing their behavior to be analyzed in various operational scenarios and testing different control strategies. In this work, the hydraulic, mechanical, electrical and electronic models of the different components of the system are studied. Two study cases for automatic flow control are assembled, using Simscape library from MATLAB/Simulink R2019b. This study cases are: i) with a control valve and ii) with a variable speed drive. The simulations determined that both cases keep the flow constant in the face of pressure disturbances, with a good dynamic response. Case 2 consumes less power than case 1, between 24 and 64% less, especially at low flow rates. It also reduce unwanted mechanical and electrical problems due to sudden starts and stops. Case 2 produced harmonic pollution on both the grid and motor sides, which implies a potential risk for the motor and the electrical grid. Case 2 was experimentally validated, obtaining errors of less than 10%.

“…Applications which require steady flow rates can be implemented by using conventional PMDC motor based centrifugal pumps together with advanced control techniques. Gevorkov et al (2018) simulated and analyzed a pump model in Simulink for a wide range of flow settings, which can be used for working on various control methods of centrifugal pump constructions. Ivanov & Erkaev (2021) constructed a mathematical model of centrifugal pump based on calculations in ANSYS Fluent software.…”

A permanent magnet direct current (PMDC) motor centrifugal pump is intended to be used as the water supply unit in a feedback linearization based coupled-tank water meter testing system. Flow rate generated by the pump corresponds to the input variable for implementing the input-output feedback linearization to this single-input-single-output (SISO) system. The pump motor is driven by an Arm Cortex M7 based microcontroller applying the pulse-width modulation (PWM) strategy at various frequencies and pwm methods. It is aimed to determine a suitable PWM frequency and driving method in order to provide a stable flow rate at the desired duty cycle values. An H-Bridge driver integrated circuit (L298N) is used in both fast decay and slow decay modes for driving the pump motor. Flow rate measurements are carried out at 4 range of frequencies between 100 Hz and 20 kHz for each mode. Fast decay mode in low pwm frequency (100Hz) results in higher deviations at the steady-state flow rate. However, slow decay mode provides a faster reduction in motor speed despite the slower current decay, which improves the flow rate stability and minimize deviations at constant pwm duty cycle values. High pwm switching frequencies increase the energy losses resulting in a lower driving voltage range, which reduces the effective range of selection for pwm duty cycle setting of flow rate adjustment. 1 kHz PWM frequency combined with the slow-decay driving mode achieves good performance in terms of linear regression and wider range for pwm duty cycle to flow rate transformation.

“…A review of existing works in the field of the simulation of the first rise sections and similar objects [16,[34][35][36][37][38][39] showed the absence of models that provide a complete analysis of the interconnections of elements of different physical nature in the complex "Electric network-Electric drive-Pump-Pipeline-Reservoir-Control system". Additionally, insufficient attention is paid to assessing the dynamic effect of the hydraulic and geometric parameters of the pipeline on the thermal properties of water in the process of automatic control.…”

The article considers the important problem of technical and economic optimization of the operating modes of the first rise section of water supply systems. At the same time, the task is to minimize the costs associated with the excessive operation of pumps, while providing the protection of the pipeline from freezing in harsh natural operating conditions. To solve this problem, a computer simulation model was developed for the first rise section, equipped with a pump performance control system. The main differences of the developed model are: integrated approach to the analysis of parameters of various physical nature, assessment of the object economic indicators, possibility of simulating non-standard control algorithms. Preliminary studies of the model have shown the possibility and feasibility of its application for calculating the optimal parameters and operating modes of the object under consideration. Based on the simulation results, it was revealed that to calculate the control action by level, it is advisable to use the PID law, for temperature—PD law, for flow rate—PI law. To calculate the main control action, it is proposed to simultaneously calculate the actions in terms of level and temperature, followed by bringing the larger of them to the value of the setpoint for the flow rate maintained by the flow controller. The studies of the proposed management concept for the first rise section have shown its high technical and economic efficiency. In particular, the savings in electricity consumption are estimated at about 55.2% while providing pipeline frost protection.
