Дослідження стійкості гідроприводу з насосом змінної продуктивності

Abstract

A new automatic regulator circuit with the combined control of a variable-displacement pump is considered. This circuit provides both pump flow stabilization and constant power mode of pump operation. Mathematical model of the variable-displacement pump control system is suggested. This model is solved using MATLAB Simulink programming environment. The influence of the system designed parameters on the transient processes has been determined as well as stability limit of the variable pump control system. Such combination of system design parameters has been determined which provides stable operation of the system throughout the whole operation range.
