“…2 To reduce the flow and pressure pulsations, which can damage the motor and its devices in the system, many researchers have optimised the structure of the plunger pump and designed control algorithms of the pump control system. [3][4][5] Qian [6][7] established a simulation model of the plunger pump using AMESim and ADAMS software. They studied the flow-pulsation dependence on the number of pistons, rotating speed and swash plate inclination angle of the axial plunger pump, and summarized the law of flow-pulsation change.…”

To improve the control accuracy and robustness of variable frequency pump-controlled motor systems, a mathematical model was built to depict the system pulsation caused by the non-uniform magnetic field of a permanent magnet synchronous motor (PMSM), the harmonic current of an inverter and the structure of a plunger pump. At the same time, system pulsations were mitigated by a novel control algorithm based on sliding mode control (SMC) and harmonic suppression compensation. In addition, the performance of the system was analysed under variable load and speed. Under low-speed and heavy-load conditions, the electromagnetic torque of the PMSM and the outlet pressure of the plunger pump fluctuated greatly by traditional controlling, with maximum deviations of 11.719 N•m and 4.63 MPa, respectively. By coordinating SMC and harmonic suppression compensation, the control algorithm reduced the electromagnetic torque and the outlet pressure of the plunger pump to 45% and 40% of the traditional pump-controlled motor system driven by variable frequency PMSM values, respectively. Furthermore, the pulsation coefficient of the PMSM output speed and the hydraulic motor output speed were both controlled within 0.2%.

When optimizing hydraulic systems, various algorithms are used, which are based on the control quality indicators selected as target functions. This is why there is a need to automate the calculation of these indicators. The article considers the main indicators of the quality of the transition process, a mathematical model of the LUDV hydraulic system is compiled and its calculation is performed in two mathematical modeling packages in order to confirm the accuracy of the initial data. An algorithm for determining the main quality indicators of the transition process has been developed, which makes it possible to simplify and speed up the optimization process of the considered LUDV-hydraulic system.
