“…However, improving the control system of the variable mechanism of swashplate axial piston pumps remains a difficult research topic at the moment [13]. This necessitates a thorough examination of the hydraulic system's dynamic properties as well as the investigation of new control algorithms and approaches [14]. At the same time, the effects of numerous parameters in the actual working environment, such as variations in temperature, pressure, and fluid viscosity, on system performance [15] must be considered [16].…”

Axial piston pumps provide a number of benefits, including strong pressure resistance, high efficiency, high transmission power, a broad speed range, and a long lifespan. These characteristics have led to their widespread usage in naval applications, construction machines, and hydraulic machinery. On the other hand, axial piston pumps frequently display reduced operating speeds as well as instability because of their inherently nonlinear properties. In this study, a mathematical model of these changeable (variable) processes is developed using a mix of theoretical calculations and acquired data. An investigation of variable mechanism control in axial piston pumps is carried out centered on robust control methods, and the controller is constructed utilizing robust H∞ theory. In terms of resilience, control precision, and system reaction time, simulations show that the H controller surpasses the PID controller.
